Abstract
A 1×N demultiplexer may include an input slab to distribute an input beam, including one or more wavelengths of light, among waveguides of a waveguide array. The wavelengths of light may comprise TE polarized light and TM polarized light. The 1×N demultiplexer may include the waveguide array to propagate a plurality of beams via the waveguides. The 1×N demultiplexer may include an output slab to cause N TE polarized beams and N TM polarized beams to be formed based on the plurality of beams. The 1×N demultiplexer may include a set of N TE output ports and a set of N TM output ports coupled to the output slab. A TE output port may receive a TE polarized beam of the N TE polarized beams. A TM output port may receive a TM polarized beam of the N TM polarized beams.
