POLARIZATION DIVERSE DEMULTIPLEXING

摘要

A method for demultiplexing an optical signal includes receiving a multi polarization optical signal, separating the multi polarization optical signal into a first polarization optical signal and a second polarization optical signal, rotating a polarization of the first polarization optical signal to match a polarization of the second polarization optical signal, routing the first polarization optical signal and the second polarization optical signal to a common demultiplexing device, outputting a channel of the first polarization optical signal and the second polarization optical signal to a common photodetector.
