Paper Abstract

We experimentally demonstrate continuously tunable optical time delay and advance using coupling-modulated microring resonators (CMR) with a 15-μm radius. By modulating the coupling coefficient through thermo-optical effect based on micro-heater, the coupling state of the microring is flexibly controlled; as a result, a large dynamic time tuning range (from time advance to delay) is achieved. The CMR device based on SOI is fabricated with commercial 0.18-μm CMOS technology. A novel micro-heater structure was firstly used to thermally tune the coupling state of the micoring. Pulse delay and advance from -15 ps to 85 ps is experimentally realized.
