Systems and methods for optical communication with polarization diversity

Abstract

Described herein are systems and techniques for a bidirectional polarization diverse optical transceivers. When an optical signal propagates along a single mode fiber, the single polarization mode gets rotated and may arrive at an optical transceiver with an arbitrary superposition of two orthogonal polarization modes, each of which experience differing optical effects. The bidirectional optical transceivers described herein include one or more features for addressing the differing optical effects so that both polarization modes are received at substantially a same time.
