Luc Thévenaz received the M.Sc. and Ph.D. degrees in physics from the University of Geneva, Geneva, Switzerland. In 1988, he joined the Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland, where he currently leads a research group (Group for Fibre Optics) involved in photonics, namely fiber optics and optical sensing. Research topics include Brillouin-scattering fiber sensors, slow and fast light, nonlinear fiber optics and laser applications in gases. He achieved with his collaborators the first experimental demonstration of optically controlled slow and fast light in optical fibers, realized at ambient temperature and operating at any wavelength since based on stimulated Brillouin scattering. He also contributed to the development of Brillouin distributed fiber sensing by proposing innovative concepts pushing beyond barriers. During his career, he stayed at Stanford University, at the Korea Advanced Institute of Science and Technology, at Tel Aviv University, at Shanghai Jiao Tong University, at the University of Sydney, and at the Polytechnic University of Valencia. In 2000, he cofounded the company Omnisens that is developing and commercializing advanced photonic instrumentation based on distributed fiber sensing.
He was member of the Consortium in the FP7 European Project GOSPEL "Governing the speed of light", was Chairman of the European COST Action 299 "FIDES: Optical Fibres for New Challenges Facing the Information Society" and Coordinator of the H2020 Marie Skłodowska-Curie Innovative Training Networks FINESSE (FIbreNErve Systems for Sensing). He is member of the Steering Committee of the International Conference on Optical Fiber Sensors and General Chairman of this conference that he hosted in 2018. He has served in the Technical Committee of several conferences, such as ECOC, CLEO-Europe, APC, etc and has been Associate Editor of Photonics Technology Letters and the Journal of Lightwave Technology. He is now co-Executive Editor-in-Chief of the journal Nature Light: Science & Applications and is Fellow of the IEEE and the Optical Society.
Jingze Yuan: First of all, congratulations！In 2020, you have a number of outstanding research results have been published in top journals such as Nature Photonics, Physical Review Letters, and so on. Your latest work with the title of "Giant Brillouin Amplification in Gases"(Ref 1, Ref 2) was also selected by OSA as one exciting breakthrough of “Optics in 2020”. In this work, your team has developed a technology based on the Brillouin Scattering in gas that can amplify light in hollow-core optical fibres. The signal is amplified up to 200 000 times and gain coefficient is at least improved by up to 6 orders of magnitude. How did you come up with such a creative idea? Did you encounter any difficulties during the research process? How did you deal with it?
Prof. Thévenaz: Actually, this was an idea floating in my mind for some 15 years, but we could not realize it before for a quite trivial combination of reasons: absence of support for this research (it remains a hopeless objective to make a visionary idea funded), unavailability of hollow-core fibres and no motivated collaborators to develop this idea. This last point was maybe the most crucial: yes, you need people in your team who believe in this idea and showing enough faith in this research! Of course, we never find what we are not curious to seek for.My original thinking was that stimulated Brillouin scattering can be quite important in a gas, since it can be strongly compressed, resulting in a higher change of density and thus refractive index – than in a solid. The secret wish was that this effect could overcompensate the penalty due to a lower material density in a gas. It is actually far from being the case at atmospheric pressure, which was fairly disappointing when we collected the first results.However, there is a quadratic dependence on pressure that we did not initially expect and was theoretically confirmed later, and this leads to a massive increase of the gain by raising the gas pressure to some tens of bars, even overcoming what can be obtained in the most efficient solid materials! This turns out to be simply the higher nonlinear gain ever obtained in a transparent dielectric material.《Light》编辑：首先要祝贺您，2020年有多项杰出研究成果在Nature Photonics, Physical Review Letters等顶级期刊发表，最新工作更是以“Giant Brillouin Amplification in Gases”(Ref 1, Ref 2)为题入选2020年度OSA光学进展“Optics in 2020”。这项工作中您的团队通过利用气体布里渊效应实现了空芯光纤里的光放大，信号放大200 000倍，增益系数比之前的工作至少提高了6个数量级。您是如何想到这样具有创造性的研究方案？研究过程中是否遇到了困难？您又是如何突破的？Thévenaz教授：实际上，这个想法一直在我的脑海中萦绕了将近15年，只是因为许多原因致使这个想法一直没有得以实现：首先这个项目缺乏资助（愿景似的构想总是很难得到资助），其次没有空芯光纤，而且也没有积极的合作者来开发这个想法。最后一点也许是最关键的一点：团队中需要有人相信这个想法并且也非常有信心来完成这个研究！当然我们只会去研究我们所感兴趣的方向。我最初的想法是，气体中受激布里渊散射效应非常重要，因为气体可以被极大地压缩，从而导致密度和折射率的变化相比于固体中更高。我们其实很希望这种效应可以补偿由于气体的低材料密度所造成的损失，但实际上，在大气压下的情况并非如此，我们测到的第一个结果让我们大失所望。气体的布里渊增益是和气压成二次方关系，我们最初并没有预料到这一点，但后来在理论上得到了证实。这就意味着，当气压升高至几十bar时，布里渊增益也会极大增强，甚至远超最有效的固体材料石英光纤。我们的分析还表明，气体的布里渊增益甚至可以超过所有的透明电介质中的非线性效应。![]()
图1 从左至右分别为：Luc Thévenaz教授、FlavienGyger博士与杨帆博士Jingze Yuan: In the special issue of OSA "Optics in 2021 & Beyond", you mentioned that "2021 will likely witness the advent of low-loss hollow-core fiber outperforming classical solid-core fibers. This will be a revolutionary breakthrough”. Would you please say something about the areas where this technology will have a profound impact in the future? What are the opportunities and challenges?Prof. Thévenaz: The idea of guiding light in vacuum or in a tenuous gas is simply luminous: the interaction with matter is reduced to a minimum value while keeping all advantages related to wave guiding such as light confinement. This means a potentially lower loss, less dispersion and less impact of nonlinear effects that all impair the capacity of an optical transmission line. The consequences will be simply optical transmission lines with higher capacities and over a longer repeater less distance.But several other advantages are not yet entirely perceived: these fibres can transmit light over a much broader spectral range, from UV to mid-IR, upscaling the capabilities for wavelength multiplexing. They are also very immune to radiation, so perfectly suitable for space applications and highly radioactive environments. This may only be the emerged tip of the iceberg: I also see another crucial advantage in the sense that these fibres can be customized, by filling them with different fluids (gas or liquid). This opens avenues for new classes of fibre devices, for lasing, optical processing and sensing.The new antiresonant hollow core fibres show now losses slightly above the attenuation of silica under single mode propagation and 2021 will hopefully see the breaking of another glass ceiling present for some 40 years, which is the 0.15 dB/km loss observed in silica. This will be a fantastic breakthrough and I am really optimisticit will happen soon thanks to the talented teams hardly working to reach this objective.《Light》编辑：OSA栏目”Optics in 2021& Beyond”中，您提到“2021年，性能优于经典实心光纤的低损耗空芯光纤即将问世，这将是革命性的突破”。可否请您谈一谈该技术将在未来哪些领域中产生深远影响？存在什么样的机遇与挑战呢？Thévenaz教授：在真空或稀薄气体中传导光的想法很亮眼：最大程度的降低光与物质的相互作用，同时保留所有与波导（如光约束）相关的优势。这也就意味我们可以获得更低的损耗，更少的色散和更小的非线性效应影响，以降低对光传输线容量的损害。其结果将是简单的光传输线将具有更高的容量和更长的无中继距离。但是还有一些其他优势尚待发掘：这些光纤可以在更宽的光谱范围内（从紫外到中红外）进行光传输，从而提高了光纤的波长复用的能力。此外，它们有良好的抗辐射性能，因此非常适用于太空和高放射性环境。这可能只是冰山一角：我还看到了另一个重要的优势，通过填充不同的流体（气体或液体），这类光纤可以按需求定制。这就为新型光纤器件、激光器、光学信号处理和传感开辟了道路。现在，反谐振空芯光纤现有的损耗仅仅比石英光纤略高，而能保证单模传输。2021年将有望实现一个近40年来前所未有的突破，比二氧化硅中0.15 dB/km的损耗极限还要低。这将是一个了不起的突破，我非常相信通过卓越团队的共同努力这一目标将很快会实现。Jingze Yuan: As a leading scientist in the field of optical fiber sensing, you have achieved the first experimental demonstration of optically-controlled slow & fast light in optical fibers, and also contributed to the development of Brillouin distributed fiber sensing by proposing innovative concepts.You have been working in this research field for more than 30 years, and achieved a lot of breakthroughs and contributions. What is your magic to stay creative in researches? So far, which research result makes you feel most satisfied? Or what’s the most memorable one to you? Why is it?Prof. Thévenaz: The process how creative ideas comes up to your mind remains mysterious for me and this is a quality that cannot be substituted by “hard working”. For sure the societal environment matters and stimulates the creativity if it leaves enough space for free thinking and the search for truth. Natural curiosity and the pleasure to challenge limits are certainly of prime importance and the creative person questions all issues, even those hurting. I am quite convinced that creative persons have somehow a rebel and iconoclastic personality, and are often subject to some degree of laziness...It is difficult to judge what my most memorable achievement is, it is like to decide which your favourite one among your children is, and you love them all! I would say that it may be the invention of the modulation technique in 1992 to synthesize all optical waves for the Brillouin interaction from a single laser. So far it was only performed using several frequency-locked lasers and the concept of synthesizing new optical waves by modulation was totally disruptive at that moment. It is now universally used for all Brillouin-based systems and certainly many current actors are totally unaware today that the technique did not come out naturally. It remains my most cited research and I am particularly proud of it, since I was fairly young at that moment and I had the deep feeling that it will be certainly impactful.Of course, the first realization of slow & fast light in optical fibres was also an exceptional strong moment in 2004. This was also a fantastic playground for research, nearly all newly collected results brought a major breakthrough. We really thought that slow & fast light may enter to the field of real applications through this achievement. However, we quickly built the conviction that slow & fast light is a bad good idea and there is no striking good application for it.Finally our very recent discovery that massive amplification can be realized in hollow core waveguides using stimulated Brillouin scattering in gases occupies a special place in my heart. This is one of the rare achievements – or maybe the only one in my career for which the results were much better than our anticipations! In addition it is so easy to implement and I am deeply convinced that it may have a strong impact in the field and even the society. The open question is to know how long it will take until the community will adopt it, if ever it does.《Light》编辑：作为光纤传感领域的学术泰斗，您不但首次通过实验验证了光纤中慢光和快光的光学控制，还提出创新性研究理念，为布里渊分布式光纤传感技术的发展奠定基础。在您从事该领域研究工作30多年中，有许多突破性的成就和贡献。您是如何保持学术创造力的？截止目前，最令您满意、难忘的工作又是什么？为什么？Thévenaz教授：对我而言，如何能提出创造性想法仍然是未知且神秘的，这是一种“努力工作”所不能取代的品质。当然，如果社会环境给自由思考留有足够的空间，那么它在激发创造力方面也会起到一定的作用。保持追求真理的好奇心和挑战极限的乐趣无疑是最重要的，富有创造力的人往往会质疑所有的问题，即使是那些伤人的问题。我十分相信具有创造力的人一定程度上都具有叛逆和打破传统的个性，而且往往在某种程度上“有些懒”……很难说我最难忘的成就是哪项，这就好比要在你的孩子们中选哪一个是你最喜欢的一样！我觉得可能是1992年发明的调制技术，可以通过单个激光器合成布里渊相互作用的所有光波。到目前为止，它只需使用几种锁频激光器就可以实现，而通过调制合成新光波的概念在当时是完全颠覆性的。现在已被广泛应用于所有基于布里渊的体系中，当然现在的许多相关科研工作者完全没有意识到这项技术并不是自然产生的。这项工作一直是我最高引的研究，我对此特别自豪，因为那时我还很年轻，但我却坚信它在未来肯定会产生深远的影响。当然，第一次在光纤中实现快慢光也算是在2004年的一个高光时刻。这也是一个极好的研究，几乎所有新获得的结果都带来了重大突破。通过这一成果，我们一度认为快慢光可以进入实际应用领域。然而，我们很快又意识到：快慢光不是一个好想法，也没有什么特别好的应用。我们最新的研究发现在我的心中也已占有举足轻重的位置：通过利用气体布里渊散射效应，我们在空芯光纤中实现了极强的光放大。这是我职业生涯中为数不多的——或者可能是唯一的——结果远超乎预期的成就！而且它很容易实现，因而我深信它可能会在该领域甚至于整个社会产生巨大的影响。但有待解决的问题是：科研界需要多长时间来接受它。![]()
图2 Luc Thévenaz教授© Alain Herzog, EPFLJingze Yuan: We know Omnisens is a world leader in high performance fiber optic monitoring. Omnisens produces instrumentation and systems based on optical metrology and photonics. Using fiber optic-based sensing, Omnisens offers continuous, reliable monitoring solutions for users in key fields such as oil, natural gas, and electric power and civil engineering facilities. As the co-founder of this company, could you please share with us about your original intention of "starting a business", as well as your impressive stories and insights?Prof. Thévenaz: I would say this is just a question of opportunity, since it was never in my plans to start a business. The idea never made me particularly excited. I was just bored that all my research results were so poorly exploited by the companies supporting my research, mostly by lack of resources and vision. So it was just the opportunist encounter of an interesting research product in my lab, some entrepreneur friends with financial resources and potential customers that decided to launch the business by founding the company.I basically dislike to mix roles and I think that I am a pure academic person, so I never took an executive position in the company and l always kept 100% active in my University position. I reckoned that I could much better give my contribution to the general society as an academic person. Logically I let the company be run by more talented persons in business, this was for me a sane sharing of competences.I am still convinced that I made the right choice and it was more beneficial for both the company and my University research group. Eventually the company is still independently running after 20 years of operation, which is quite a success.《Light》编辑：瑞士Omnisens公司是分布式光纤传感领域的世界领导者。Omnisens先进的分布式光纤监测系统可为石油、天然气、电力和土木工程设施等关键领域的用户提供实时有效的资产完整性监测解决方案。作为公司的联合创始人，您可以和我们分享一下您“创业”的初衷，以及您认为印象深刻的故事和感悟吗？Thévenaz教授：这其实只是个机遇问题，因为创业从来都不是我的计划，这个想法也并没有让我觉得很兴奋。我只是厌倦了我的所有研究结果无法被支持我研究的公司充分利用与开发（主要是因为缺乏资源和远见）。当一些有资金和潜在客户的朋友们在我的实验室里发现了他们的感兴趣的研究时，他们决定通过创立公司来开展业务。这就是Omnisens创立的过程。我其实不喜欢有多重身份，我认为我是一个纯粹的学者，所以我从没在公司担任行政职务，只是全力以赴地做好我在大学里的研究工作。我认为我作为一名学术人员能更好的为社会做贡献。我让更多的商业人才经营公司，这对我来说是一种更为理智的能力分配。我始终坚信我做出了正确的选择，这对公司和我在大学的研究团队都更加有利。历经20年后，Omnisens公司仍然可以独立运营，这无疑是相当成功的。Jingze Yuan: In January 2016, you published your research work Ref. 3 in Light for the first time.In July 2018, we were honored to successfully invite you to serve as the co-executive editor of Light. From the author to the EIC, you have contributed to the development of Light for almost 5 years, and we have also developed a close and a deeper friendship. Could you still recall the story about your first contact with Light? How do you appraise this Journal? What is your expectation to Light?Prof. Thévenaz: I was actually informed at an early stage about the Light project, maybe in 2009 or 2010, during a casual conversation with my old friend Rachel Won, Editor for Nature Photonics. I found it a brilliant idea, since there was no real space for the publication oftop quality applied photonics research. I thought at that moment that my next experimental breakthrough would be for that journal, and it turned out to be the case.Later, I had strong cases of disagreement with editorial decisions (as author and reviewer!) and, instead of taking a break-up attitude, I found more constructive to bring my support by joining the editorial team, because I deeply believe in the potentiality of the journal and a little help may make the difference to reach excellence.This can be maintained by never compromising on some principles: consider only breaking novelties with respect to the state-of-the-art, introducing entirely novel concepts, and a careful choice of independent and experienced reviewers.《Light》编辑：2016年1月，您首次在Light期刊上发表研究成果Ref. 3。2018年7月，我们非常荣幸地邀请到您担任Light期刊共执行主编。从作者到主编，近5年的时间里，您为Light的发展献力献策，我们也建立了更紧密的联系和更深厚的情谊。您是否还能回忆起最初与Light结缘的故事？您对Light期刊如何评价？又有哪些期待呢？Thévenaz教授：早在2009年(或2010年)与老朋友Rachel Won（Nature Photonics编辑）的一次闲聊中我就了解到了Light的创刊计划。我觉得这是一个非常棒的想法，因为当时的确还没有一本真正以发表光学领域重大应用研究为目标的高水平期刊。那个时候我就想，我的下一个突破性实验成果要发表在Light上，事实上我们也确实是这样做的。之后，我作为作者和审稿人，都曾与编辑部在稿件决策问题上产生较大的分歧。与其抱着与Light决裂的态度，我发现加入编辑团队来支持期刊的发展应该是更有建设性的解决方式。因为我深信Light的潜力，我的一些帮助也许有助于期刊成就卓越。当然想要保持卓越就不能在一些原则问题上做丝毫的妥协与让步：只发表与最先进技术相关研究工作、或展现全新概念的创新突破，同时谨慎选择公正且经验丰富的审稿人。![]()
图3 第26届光纤传感国际会议(OFS, EPFL),大会主席Luc Thévenaz教授到访Light期刊展位，并宣传期刊Jingze Yuan: As the leader of an outstanding scientific research team, how do you allocate time to your students and collaborators? You have cultivated many excellent scientific researchers in the optical fiber field. What do you think is the most important thing a mentor should offer to his/her students?Prof. Thévenaz: First you have to know that, according to the EPFL organizational scheme, my team is small: maximum 5 students and 2 postdocs. It means I have time to meet and to have a personal contact with all members of my team. My office room is next to the lab and the door is always opened, so my people can always come and I let them know they are my priority. We have no formal group meetings (or very occasionally), but we have the tradition to share the lunch together all sitting around the same table. It is the time to have informal discussions,related to our activities of course, but also to address all topics of discussion, even on social and political themes. This is a very enriching moment, since the members of my teams come from very different origins in 4 continents. We debate about everything! I learned a lot about the different ways of thinking and of handling situations in different cultures.I am convinced that a stimulating attitude is constitutive of a good mentor: you must help them when they face a difficulty, suggesting a solution when needed and giving complementary knowledge. And never be too directive and give useless pressure, and always have a constructive and rewarding attitude. A stressed and depressed researcher never makes a good job and the absence of human warmth is definitely a killer for creativity.《Light》编辑：作为一个杰出科研团队的领导者，您平时是怎样分配时间给您的学生和合作者的呢？您已经在光纤领域内培养了许多优秀的科研人才，您觉得好的指导老师最应给予学生的是什么？Thévenaz教授：根据EPFL的组织架构要求，我的研究团队很小：最多5名学生和2名博士后。这意味着我有较为充分的时间和我团队的每位成员接触。我的办公室就在实验室旁边，办公室的门也总是开着的，我的团队成员随时可以进来，而且我会以他们为先。我们没有正式的（或者极偶尔有）组会，但我们有同桌共进午餐的习惯。我们会利用这个时间进行一些非正式的讨论，当然会与我们的工作有关，但是也会讨论到其他各种话题，甚至涉及一些社会和政治议题。每当这时我都感到非常充实，因为我的团队成员来自4个大洲的不同地区，我们什么事都会讨论！在不同的文化中，我学到了很多不同的思维方式和解决问题的方法。我相信，善于激励是一位好导师必要的素养。导师应该在学生面临困难时给予帮助，在必要时为学生提出解决方案，并教授他们所需要的知识。更不要总是命令学生，也不要给学生施加无谓的压力，应该始终以积极和鼓励的态度来对待学生。要知道，一位压力大、情绪低落的研究人员永远做不出好的研究成果，关怀与温暖的缺失绝对是创造力的杀手。![]()
图4 Luc Thévenaz教授与团队成员登山郊游Jingze Yuan: We know you are used to visit China and also have cooperated with some Chinese Institutes, such as Shanghai Jiao Tong University, Beijing University for Post and Telecommunications, University of Electronic Science and Technology of China, Huazhong University of Science and Technology, Jinan University, etc. Could you please talk something about yourcooperativeprojects?What are your criteria and requirements for choosing overseas collaborations? If it’s possible, would you like to consider to establish cooperation with our CIOMP?Prof. Thévenaz: My team is involved in a certain number of projects with Chinese partners, some formal, some informal, but with a great variety of objectives and frameworks. Some are very prestigious such as the 111 project with UESTC in Chengdu. Above all I appreciated hosting junior and even senior researchers through theCSC support: it was a very fertile way to collaborate and certainly an intensive experience for the visitors.By principle I am practicing science and sharing experiments indifferently with any human beings and my motivations are fully philanthropic, implicitly setting a limit to my collaborations: it must contribute to the universal welfare, and not only for local benefits or promotions, and even less for military purposes. So I have fundamentally no issue about setting a collaboration with CIOMP (I recently participated to a workshop during the visit of a delegation from CIOMP at EPFL), if this is something profitable for the entire mankind!On a more general point of view I find quite fascinating to experience and to challenge our mutualcultural visions, which are more similar than expected at first glance. I always felt that our senses of friendship and commitment are quite comparable. And of course I have a big admiration for the millennial culture of China, for the quick technical development of the country due to the exceptional qualities of hard working among Chinese people, taking their personal development in their own hands. On the other hand the limits set to curiosity do not favour a fertile ground for creativity. In general knowing others having a different cultural background humbly puts a light on your own limits, but also on your qualities, this is an extremely enriching personal experience.《Light》编辑：您经常到访中国，并与国内多所高校，包括上海交通大学、北京邮电大学、电子科技大学、华中科技大学及暨南大学等有学术合作。可否请您谈一谈这些合作项目？您是基于什么样的原则标准来选择合作伙伴？如果有合适的机会，您是否愿意和中科院长春光机所合作？Thévenaz教授：我的团队参与了一定数量的中方项目，有正式的，也有非正式，合作的目标和框架各不相同。其中包括一些知名的项目，如成都电子科技大学的111项目。而最为重要的，我很感谢能有机会接收由中国国家留学基金委等支持的访问学者，并与之合作，在我看来这是一种非常有益的合作方式，当然对访问者来说也是一次充实、有益的经历。原则上，我从事科学研究并愿与所有人一起分享我的实验成果，但我的初衷一定是公益性的，这在无形中也为我的合作设置了一个条件：合作的目的须为普世性福祉做出贡献，而不仅仅是为了当地的发展利益，而对军事目的的考量则更少。所以，如果是在对人类社会发展有益的事情上合作，我很乐意与中科院长春光机所携手（而且我最近也参加了CIOMP代表团在EPFL访问期间的一个研讨会）。我发现体验和挑战不同国家/地区的文化视野非常有趣，其实我们的文化背景比最初预期的更为相似。我坚信我们对友谊和责任感有着同样的认知。我也非常钦佩中国悠久的历史文化，钦佩中国科技的快速发展，这些都是基于中国人民勤勉的卓越品质，紧紧掌握着自己的命运。从另一方面来说，限制好奇心将不利于创造力的培养。总的来说，通过了解有着不同文化背景的人，能使人谦逊地明白自己的局限与优势，这是一种大有裨益的个人经历。![]()
