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 14):
The system of  claim 13 , comprising a difference in frequency between the laser carrier signal and the SBS signal, wherein the laser carrier signal and the SBS signal incident on the photodetector generate beats with a beat frequency in the RF range at the photodetector, the beat frequency corresponding to the difference in frequency between the laser carrier signal and the SBS signal, and wherein the electrical signal from the photodetector includes a frequency in the RF range corresponding to the beat frequency between the laser carrier signal and the SBS signal.
