Nonlinear chalcogenide optical devices

4:15 p.m. 

I will discuss my research interests in nonlinear chalcogenide devices and ultrafast spectroscopy. Recently, ultrafast and nonlinear integrated devices have captured interest for frequency metrology, sensing, and imaging. An excellent platform for nonlinear optical devices is offered by chalcogenide glasses, with high nonlinearities, long wavelength transparencies, flexible substrate choice, and low nonlinear absorption. Progress on integrated optical devices for the near, mid, and long-wavelength infrared is presented, including nonlinear optical characterization. Ultrafast spectroscopy of chalcogenide materials and III/V semiconductors will also be discussed.

Bio: Juliet Gopinath is an Associate Professor of Electrical, Computer and Energy Engineering at the University of Colorado Boulder. She received her B.S. degree in Electrical Engineering from the University of Minnesota and her M.S. and Ph.D. degrees at MIT. She was a member of technical staff at MIT Lincoln Laboratory from 2005 to 2009. Since then, for the past nine years, she has led a research group at the University of Colorado Boulder. Her current research interests include ultrafast lasers, nonlinear optics, mid-infrared materials, spectroscopy, orbital angular momentum and adaptive optical devices. She is the recipient of an R&D 100 Award (2012), an NSF CAREER Award (2016) and the University of Colorado Boulder Provost's Achievement Award (2016). She has published 52 peer-reviewed journal articles and served as an Associate Editor for the IEEE Photonics Society Journal (2011-2017) and a member of the IEEE Photonics Society Publications Council (2018). She is currently the Associate Director for Cubit, the University of Colorado Boulder Campus Quantum Initiative.
