Abstract:
In one example embodiment, an integrated silicon photonic wavelength division demultiplexer includes an input waveguide, an input port, a plurality of output waveguides, a plurality of output ports, a first auxiliary waveguide, and a plurality of auxiliary waveguides. The input waveguide may be formed in a first layer and having a first effective index n 1 . The input port may be optically coupled to the input waveguide. The output waveguides may be formed in the first layer and may have the first effective index n 1 . Each of the output ports may be optically coupled to a corresponding output waveguide. The first auxiliary waveguide may be formed in a second layer below the input waveguide in the first layer. The first auxiliary waveguide may have a second effective index n 2  and may have two tapered ends, and n 2  may be higher than n 1.
