    Prof. Hartmut Bartelt
    (Leibniz Institute of Photonic Technology, Germany)

    "Technology and Applications of Fiber Bragg Grating Sensors in Germany"

    Biography: Prof. Dr. Hartmut Bartelt graduated in Physics from University of Erlangen-Nuremberg (Germany) in 1976 and received his PhD for research on wavelength multiplexed optical signal processing in 1980. From 1981 to 1982 he worked as a research assistant at the University of Minnesota in Minneapolis (USA) in the field of volume holographic optical elements. In 1982 he returned to the University of Erlangen-Nuremberg to continue his research activities and in 1985 he joined the corporate research laboratories of Siemens AG in Erlangen (Germany).
    In 1994 he was appointed professor for Modern Optics at the University of Jena (Germany) and became head of the Optics Division of the Institute for Physical High Technology (IPHT), now Department of Fiber Optics in the Leibniz Institute of Photonic Technology (IPHT). From 1999 until 2006 he served as director and since 2006 as deputy director of the institute. His research activities cover the fields of optical speciality fibres, micro and nano-structured fiber optics, fiber light sources, fiber Bragg gratings and fiber optical sensors.

    Abstract:Fiber Bragg gratings have been proven to be extremely versatile elements for manifold sensing applications. They provide localized and fiber integrated sensing functionalities in combination with easy multiplexing capabilities. Applications for many different physical parameters and stability also under extreme conditions have been shown. Such attractive properties have resulted successfully in specific commercialization activities in Germany which provide a good example how to develop industries in the field of optical sensing.

    Prof. Yanqing Lu
    (Nanjing University, China)

    "Liquid crystal for non-display photonic applications"

    Biography: Yanqing Lu received both his BS and Ph.D. degrees from Nanjing University, China, in 1991 and 1996 respectively. He has five-year experiences in US and China telecomm industries. He designed and developed a serial of liquid crystal based fiber-optic devices with his colleagues, which include variable optical attenuators, variable Mux/Demux, DWDM wavelength blocker etc. He is currently a Changjiang distinguished professor at Nanjing University and a Fellow of OSA. His research interests include liquid crystal photonics, fiber optics and nonlinear optics. He is the author or co-author of ~150 peer-reviewed papers in Science, Adv. Mater., Optica, Phys. Rev., Appl. Phys. Lett., Opt. Lett. etc. with over 2000 citations. He also holds more than 40 domestic or international patents or pending patents.

    Abstract:Inducing micro-patterns and structures inside a Liquid crystal (LC) cell is an effective way to improve the performance of LC display. However, in addition to display applications, LC also plays an important role in various tunable photonic devices with the advantages of low cost, no moving parts, low power consumption and high reliability. In this talk, I am going to review some of our work in merging LC and various artificial microstructures in different spans. The related photonic applications are discussed.

    Prof. Kaoru Minoshima
    (University of Electro-Communications, Japan)

    "Ultra-precision control of optical waves by use of fiber-based frequency combs and its application"

    Biography: Prof. Kaoru Minoshima is a Professor at the University of Electro-Communications (UEC), Tokyo, Japan, since 2013. She is also the Research Director of MINOSHIMA Intelligent Optical Synthesizer Project (IOS), Exploratory Research for Advanced Technology (ERATO), Japan Science and Technology Agency (JST). She received her Ph.D. degrees from the University of Tokyo in 1993, and joined the National Research Laboratory of Metrology (NRLM), which was reorganized to the National Institute of Advanced Industrial Science and Technology (AIST), where she has served as Group Leader and Bureau Manager until 2013. She also served as a Visiting Professor at the University of Bordeaux I, France (1996), a Visiting Scientist at the Massachusetts Institute of Technology, USA (2000-2001), and a guest professor at the Tokyo University of Science (2007-2013).
    Her areas of research are ultrafast optical science and technology and their application to optical metrology, particularly time-resolved imaging, generation and application of frequency combs.
    She received the Prize for Science and Technology given by the Minister of Education, Culture, Sports, Science and Technology (MEXT), Japan, in 2008, and the first Women Scientists Award from the Japan Society of Applied Physics (JSAP) in 2010, and so on. She served as several international committees including the General Co-Chair of the Conference on Lasers and Electro-Optics (CLEO) 2011. She is a member of the Science Council of Japan and a Fellow of the Optical Society (OSA) and JSAP.

    Abstract:Optical frequency combs have opened up several new application fields not only in frequency metrology as “ultraprecise frequency ruler” but also in broad area by use of its capability for fully controlling the phase, time, and frequency information of light waves, i.e., “optical synthesizer”, with an extreme precision and wide dynamic range. In this talk, development of fiber-based frequency combs, which are the key for practical application is presented. Moreover, some of the applications of frequency combs, including precision spectroscopy for gas sensing and material characterization, distance measurement, and imaging are presented.
