Abstract
A method and system for providing an isolator/polarization beam deflector is disclosed. The method and system include a first collimator, a core and a second collimator. The first collimator collimates a plurality of optical signals traveling in a first direction. The core receives the optical signals from the first collimator. The core includes first and second birefringent wedges and a rotator between the first and second birefringent wedges. The first collimator, the first birefringent wedge and the rotator transmit the optical signals such that the optical signals cross at an interface between the rotator and the second birefringent wedge. The core transmits the optical signals with a deflection, combines the optical signals to provide a combined optical signal and prevents a reflected portion of the optical signals from traveling opposite to the first direction. The second collimator receives and couples the combined optical signal to the output.
