内容摘要:
 
    The optical micro-ring resonator, first proposed in 1969 as a simple filter, has now been demonstrated to be a versatile device capable of performing all the common functions in communications and signal processing:  filtering, multiplexing/demultiplexing, modulation, switching, delay, gating, routing, sensing, amplification.  The small dimensions of the rings place them in a very interesting operational parameter range: wide bandwidth yet high finesse. These properties are especially attractive for nonlinear optical applications. The high finesse means high stored intensities in the rings as in any resonator, which is further enhanced by the small model area, yet the bandwidth is not sacrificed.  Small and easy to fabricate with planar technology, 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.  The talk will conclude with a discussion on the challenges  and prospects of this technology.   
Prof. P.-T. Ho简介:
P.-T. Ho is a visiting professor in Tsinghua University, on leave from the University of Maryland, College Park, USA.  He specializes in optics, and his technical accomplishments  include the first mode-locking of the semiconductor laser, the first mode-locking and amplification of the CW Nd:glass laser, the discovery of several transient switching phenomena in optical bistability, the first optically addressed spatial light modulator at 1.5 m, the extension of the Schawlow-Townes formula to the mode-locked laser and its experimental verification, the quantum theory of gyrotrons and of free electron lasers, the quantum Child-Langmuir law, reconfigurable antennas, and high power diamond and ZnS switches.  In recent years he has been working on optical micro-ring resonators, being the first to demonstrate high-order filters and many other linear and nonlinear devices.  .
