Patent Images
1. An optical structure, comprising:
- a polarization beam splitter comprising an input end, and an output end having a first output and a second output;
a polarization rotator system comprising a first polarization rotator having an input end and an output end, and a second polarization rotator having an input end and an output end; and
a polarization beam combiner comprising an input end having a first and second input, and an output end; and
wherein the first output of the polarization beam splitter is operatively connected to the input end of the first polarization rotator, and the output end of the first polarization rotator is operatively connected to the first input of the polarization beam combiner; and
wherein the second output of the polarization beam splitter is operatively connected to the input end of the second polarization rotator, and the output end of the second polarization rotator is operatively connected to the second input of the polarization beam combiner.

Abstract
A polarization beam splitter-polarization rotator-polarization beam combiner optical structure comprising a pair of polarization rotators having a polarization beam splitter associated with the input ends of the two polarization rotators, and a polarization beam combiner associated with output ends of the two polarization rotators, and a method of purifying a light signal comprising TE and TM modes by disassociating the primary TE and TM modes from first order splitter and rotation error components.
