Two-channel integrated photonic wavelength demultiplexer

At least one non-transitory machine-accessible storage medium that provides instructions that, when executed by a machine, will cause the machine to perform operations for producing a schematic representative of a photonic demultiplexer, the photonic demultiplexer comprising:

• an input region configured to receive a multi-channel optical signal including a first wavelength channel and a second wavelength channel different than the first wavelength channel;
• a dispersive region optically coupled to the input region, wherein the dispersive region includes a first material and a second material inhomogeneously interspersed to form a plurality of interfaces that each correspond to a change in refractive index of the dispersive region and collectively structure the dispersive region to optically separate the first wavelength channel and the second wavelength channel from the multi-channel optical signal when the input region receives the multi-channel optical signal;
• and
• at least two output regions, including a first output region and a second output region, each optically coupled to the dispersive region, wherein the first output region is positioned to receive, from the dispersive region, the first wavelength channel demultiplexed from the multi-channel optical signal, and wherein the second output region is positioned to receive, from the dispersive region, the second wavelength channel demultiplexed from the multi-channel optical signal,
• wherein the schematic is producible by a feature shape with a predetermined width.
