Stable photonic millimeter-wave generation using an integrated reciprocating optical modulator

We investigated stability and phase noise of V-band millimeter-wave generated by using a hybrid integrated reciprocating optical modulator consisting of a pair of fiber Bragg gratings and a LiNbO/sub 3/ optical phase modulator. The amplitude fluctuation of generated millimeter-wave was less than 1% without using feedback stabilization technique. Phase noise of the millimeter-wave was -74.3 dBc/Hz at 10-kHz offset.
