Biography:

Dr. Kavita Devi is an Assistant Professor in the Department of Physics at Indian Institute of Technology (IIT), Dharwad. She received M.Sc. in physics from IIT Guwahati, India, and completed her Ph.D. in photonics at ICFO–The Institute of Photonic Sciences, Spain, where she also spent time as a postdoctoral research fellow. Prior to joining IIT Dharwad, she worked as a Ramanujan Fellow at IIT Bhilai. Dr. Devi’s research interests include optical parametric oscillators in all time scales, nonlinear frequency conversion, frequency comb generation and nonlinear optical properties of novel materials.  She is a senior member of Optica (formerly OSA), professional member of SPIE, and lifetime member of OSI- Optical Society of India, ILA- Indian Laser Association, and PSSI- Plasma Science Society of India. She has authored and coauthored more than 70 papers, presented in peer-reviewed scientific journals and conferences that include CLEO-USA and CLEO-Europe, and also served on the technical committee of CLEO-USA many times.

Lecture: "Exploratory Nonlinear Optical Device Architecture and Properties"

Nonlinear optical devices, in particularly optical parametric oscillators (OPOs) are very well recognized as viable sources of widely tunable radiations in all time-scales from continuous-wave (cw) to ultrafast domain. For further advancement of such devices, there is always a quest of finding low- cost architectures in a compact design. Additionally, given that the nonlinear optical properties of materials are the key parameter of interest in many photonic devices, the study of these properties with a cost-effective technique is desirable. In this talk I would discuss the design consideration and analysis of a low-cost, broadband, multiaxial-mode, passively-stable cw OPO. Further the determination of nonlinear optical properties in a compact, cost-effective design with the challenges associated will be discussed.
