High-Q Silica Optical Resonators for Integrated Optomechanical Oscillators

Optical microring/disk resonators are the central component in many micro-optical applications, including optomechanical devices and tunable-bandwidth filters. Optomechanical devices, which use light to stimulate mechanical resonance, could potentially be applied to chip-scale atomic clocks. Tunable-bandwidth filters are a key enabling component for optical access networks. For example, they can be used to control wavelength channels or allocate bandwidth dynamically. High optical Q is necessary for both of these applications, so we are exploring the use of silica, which has low optical loss. So far, we have achieved an optical Q of one million and have observed self-excited optomechanical oscillations.
