Over the past decade, photonic integrated circuits have found a variety of new application areas, including many different types of sensing systems. Photonic integration has enabled new functionality, as well as reduction in size, weight and power (and eventually cost) of these new systems. In this talk, we will provide an overview of a variety of cutting edge PICs for sensing applications, with the focus on some of the recent technology that we have developed in this arena.
Dr. Leisher is Vice President of Research for Freedom Photonics, LLC in Santa Barbara, CA. Prior to joining Freedom Photonics, Dr. Leisher was Chief Engineer for Diode Lasers at Lawrence Livermore National Laboratory (Livermore, CA) where he served as the principal subject matter expert for high power diode laser technology and led the diode group in support of several research and development programs. From 2011-2017, Dr. Leisher served as Associate Professor of Physics and Optical Engineering at Rose-Hulman Institute of Technology (Terre Haute, Indiana) and as the Manager of Advanced Technology at nLight Corporation (Vancouver, Washington) from 2007-2011. He received a B.S. degree in electrical engineering from Bradley University (Peoria, Illinois) in 2002, and a M.S. and Ph.D. in electrical and computer engineering from the University of Illinois at Urbana-Champaign in 2004 and 2007, respectively. Dr. Leisher’s research interests include the design, fabrication, characterization, and analysis of high power semiconductor lasers and other photonic devices. He has authored over 230 technical journal articles and conference presentations and served as the principal investigator on approximately 50 funded research projects in the area of photonics and semiconductor laser technology. He has served on the technical committee of many conferences including IEEE Photonics Conference, IEEE International Semiconductor Laser Conference, IEEE High Power Diode Lasers & Systems Conference, and OSA International Optical Design Conference. He is the co-chair of the SPIE Components and Packaging for Laser Systems Conference and is the program track chair for the SPIE LASE Symposium Nonlinear Optics and Beam Guiding conferences. Dr. Leisher is a senior member of both SPIE and IEEE.
