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 11):
An optoelectronic oscillator system comprising:\n a laser source for providing a laser signal; an optical modulator having at least one optical input, at least one optical output, and at least one electrical input, the laser source communicating with the optical input of the optical modulator via an optical communication path such that the laser signal passes through the optical modulator to produce a modulated laser signal; an optical subunit including a Stimulated Brillouin Scattering (SBS) medium, the optical subunit having an output optical signal; a photodetector that produces an electrical signal responsive to light incident upon the photodetector; and an optical circulator that optically communicates with the optical output of the optical modulator such that the modulated laser signal from the optical output of the modulator is conducted to the optical circulator along an optical path, wherein the optical circulator optically communicates with the SBS medium so that the modulated laser signal is conducted from the optical circulator to the SBS medium, wherein the photodetector optically communicates with the optical subunit so that the output optical signal of the optical subunit is communicated to the photodetector to generate a corresponding electrical signal, and wherein the photodetector electrically communicates with the optical modulator to allow the electrical signal from the photodetector to be communicated to the electrical input of the optical modulator to modulate the laser signal.
