Photonic clocks, Raman lasers, and Biosensors on Silicon

Micro-resonators on silicon having Q factors as high as 500 million are described, and used to demonstrate radio-frequency mechanical oscillators, micro-Raman and parametric sources with sub-100 microwatt thresholds, visible sources, as well as high-sensitivity, biological detectors

Micro lasers on a silicon chip

Micro-resonators on silicon having Q factors as high as 500 million are described, and then are used to demonstrate micro-Raman and parametric sources with sub-100 microWatt thresholds, as well as a novel radiation-pressure driven micro-mechanical oscillator
