Opto-Acoustic Oscillator Using Silicon Mems Optical Modulator

摘要

We show operation of a silicon MEMS based narrow-band optical modulator withlarge modulation depth by improving the electro-mechanical transducer. Wedemonstrate an application of the narrowband optical modulator as both thefilter and optical modulator in an opto-electronic oscillator loop to obtain a236.22 MHz Opto-Acoustic Oscillator (OAO) with phase noise of -68 dBc/Hz at 1kHz offset.
