Abstract

An integrated optical polarization beam splitter/combiner and isolator (IPBC) is disclosed. In one disclosed aspect, the IPBC may comprise a first birefringent crystal optically configured to receive two rays incident at an angle, a rotator configured to rotate the rays received, and a second birefringent crystal positioned to receive the rays from the rotator. The IPBC may be configured to combine the rays in a forward direction, and isolate said two rays in a reverse direction.
