Abstract
The present disclosure provides a wavelength division multiplexing (WDM) device for demultiplexing an optical signal including a plurality of wavelength channels. The device comprises at least one demultiplexer block configured to provide, for each wavelength channel of the optical signal, two half-channel signals. The device further comprises a mode mapping block configured to map one half-channel signal related to a split wavelength channel into a first polarization mode, and the other half-channel signal related to the same split wavelength channel into a second polarization mode. The device also comprises an output block for each wavelength channel, each output block being configured to combine polarized half-channel signals related to the same wavelength channel.
