Abstract
System and techniques for reducing the polarization dependency of an optical component by combining the actions of a circulator and a polarization beam combiner to separate an optical signal into a plurality of orthogonally oriented polarization components; rotate at least one of the components so that the polarization orientation of the components are parallel; propagate the components through respective input ports of an optical component at substantially the same time; rotate at least one of a plurality of output components from the optical component so that the polarization orientation of the output components are orthogonal; and recombine the plurality of output components into an output optical signal.
