Classification: CPC H  G | IPC G  H

Claim 0:
1. A photonic device, comprising:
an input region adapted to receive an optical signal including a multiplexed channel, the multiplexed channel characterized by a distinct wavelength;
a dispersive region, optically coupled with the input region to receive the optical signal, the dispersive region including a plurality of sub-regions defined by an inhomogeneous arrangement of a first material and a second material; and
a plurality of output regions, optically coupled with the input region via the dispersive region;
wherein:
the plurality of sub-regions include an input channel section, one or more coupler sections, and one or more branching sections;
the plurality of sub-regions together configure the photonic device to demultiplex the optical signal and to isolate the multiplexed channel at a first output region of the plurality of output regions; and
the one or more coupler sections includes a first coupler section, the first coupler section including a channel of the first material, wherein the first coupler section is optically coupled to a first branching section included in the one or more branching sections, and wherein the channel of the first material branches into at least two separate channels of the first material within the first branching section.
