An optical regeneration scheme based on non-degenerate phase-sensitive amplification in highly-nonlinear fibers is proposed. The regenerator exhibits significant amplitude and phase noise suppression properties and eliminates the need for precise phase and frequency locking with the input signal.
We demonstrated low phase noise millimeter-wave generation by using an reciprocating optical modulator. A lightwave modulated by 44 GHz millimeter-waves was obtained from a microwave signal, with low phase noise of -88.5 dBc/Hz at 10 kHz offset.
We describe a self-starting optical pulse source generating 10 GHz, 15 ps pulses with an average jitter of 43 fs and a 0.15% amplitude noise over a frequency range of 500 Hz-1 MHz
