Title: Optical Micro-ring Resonators

　　Speaker: Prof. P.-T. Ho（Electrical engineering in the University of Maryland, College Park, USA）

　　Venue: Academic Salon, Institute of Semiconductors, CAS

　　Abstract: Optical micro-ring resonators are compact, versatile devices capable of performing all common functions, linear and nonlinear: filtering, multiplexing/demultiplexing, modulation, switching, delay, switching, gating, routing, sensing. They are particularly suitable for large-scale integration. After a brief introduction to micro-resonators in general and micro-ring resonators in particular, I will present our work in Maryland as well as work elsewhere. I will conclude with a discussion on the prospects and challenges of this technology.
