Abstract :
We present optically-controlled extinction ratio (ER) and Q-factor tunable silicon microring resonators using optical forces. Two opto-mechanical structures are studied, i.e. double-clamped and cantilever. A wide ER tuning range from 5.6 to 34.2dB is achieved. Low control power of 1.4mW is required for cantilever structure.
