Opto-Electronic Oscillator And Method

An opto-electronic oscillator circuit, comprising:

• an opto-electronic circuit loop including a transistor laser optical modulator that receives a first electrical signal and produces a laser optical output signal coupled with a transistor optical amplifier, a photodetector optically coupled with said transistor optical amplifier, and a phase shifter coupled with said photodetector for producing a phase shifted signal that is fed back to said transistor laser as said first electrical signal;
• and
• an optical loop comprising an injection locking optical resonator optically coupled with said transistor optical amplifier.
