Patent ID: 8824901

Claim:
A multi-mode optoelectronic oscillator (MM-OEO), comprising: an OEO cavity having an input for receiving an RF signal and an RF output, said OEO cavity comprising: a first laser having a first laser output; a second laser having a second laser output; a modulator having a first input coupled to the first laser output, a second input coupled to the second laser output, a third input, and having a first modulator output and a second modulator output; a semiconductor optical amplifier (SOA) having an input coupled to the first modulator output and having an SOA amplified output; a photodetector coupled to the SOA amplified output and having an output; and a coupler having an input coupled to the photodetector output and having a first output coupled to the third modulator input and a second output, whereby an amplified RF signal is produced at the OEO RF output.
