Abstract
A method is proposed where isolation of a single-frequency laser from reflections of an optical network is obtained using reciprocal elements throughout. The principle is based on the isolation obtained by a double transit quarter-wave plate, which can be generalized. Only linearity and time invariance are required. Thus the network elements can even be nonreciprocal. An application is the isolation of the local-oscillator laser in an integrated optical heterodyne/homodyne receiver
