Abstract
An all optical radio frequency converter. The invention relates to a microtoroid optomechanical oscillator that can provide a local oscillation frequency and a mixing functionality. The microtoroid optomechanical oscillator can be fabricated from a silica-on-silicon wafer. When an input optical signal having an optical carrier frequency carrying a modulated RF signal representing information is applied to the microtoroid optomechanical oscillator, a signal including the baseband information modulated on the optical carrier is provided as output. The output signal can be detected with a photodetector. Information carried by the optical signal can be recorded and/or displayed to a user. Injection locking of the microtoroid optomechanical oscillator can be accomplished by providing a signal of suitable frequency. The frequency and the phase of operation of the microtoroid optomechanical oscillator can be locked to the respective frequency and phase of the injected locking signal.
