Abstract

A technique is described and experimental evidence presented for obtaining ultrahigh isolation between the optical local oscillator and the transmitter in heterodyne systems. A degree of isolation that results in an equivalent fedback optical signal that is more than 200 dB below the transmitted power level has been achieved.
