Abstract

A technique is described for using polarization beamsplitters to mix the signal and local oscillator light beams in coherent differential detection systems. When the signal polarization and alignment states are uncertain, this scheme offers performance improvements over techniques using amplitude beamsplitters. In its most elaborate form, it offers the possibility of sensing the polarization state of the incoming signal, and therefore controlling it in the receiver.
