Abstract:
An architecture for an optoelectronic oscillator uses Stimulated Brillouin Scattering (SBS) to seed, filter and amplify the oscillation signal in an overlapped oscillator loop for both a RF modulated optical sideband and a SBS signal. By phase matching the RF modulated optical sideband generated by SBS with the SBS signal, the feedback will collapse the bandwidth of the SBS signal and in turn the bandwidth of the Brillouin frequency signal, which also serves as a filter to filter out multiple undesired OEO loop modes. The embodiments herein result in reduced phase noise and increased stability.

Claim (Index 7):
The method of  claim 2 , comprising providing an optical subunit comprising a combined tunable time delay or optical phase shifter and reflector device, wherein the reflector is part of the combined tunable time delay and reflector device, wherein the modulated laser signal has at least one sideband having a frequency, wherein the laser modulated signal has at least one laser carrier signal having a laser frequency, wherein the laser carrier signal generates an SBS signal through stimulated Brillouin backscatter of the laser carrier signal as the laser carrier signal interacts with the SBS medium, and wherein the method further comprises tuning the optical subunit to phase match the sideband reflected by the reflector to the SBS signal in order to interlock the oscillation mode of the optoelectronic oscillator with a SBS resonant frequency mode.
