A new OEO design using optical phase modulation and modulation suppression

Abstract

We present the design for a phase-modulated Opto-Electronic Oscillator (OEO) that incorportes 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.
