A New OEO Design Using Optical Phase Modulation and Modulation Suppression

We present the design for a phase-modulated opto electronic oscillator (OEO) that incorporates asymmetric Mach-Zehnder (AMZ) interferometers as phase demodulators together with PM modulation suppression. The new design promises to obtain in the electro-optical domain the low-noise advantages previously achieved in RF and microwave oscillators by the use of carrier suppression but which have been achieved only to a limited extent in OEO's
