We present the design and fabrication of a SOI ultra-compact wavelength-demultiplexer based on arrayed-waveguide-gratings. The size of device is <0.1 mm2 and the simulation shows that crosstalk is >30 dB between channels and insertion loss is ~1 dB.
Compact wavelength multiplexers/demultiplexers using photonic wires in add/drop filter and multi-mode interferometer (MMI) configurations were demonstrated on SOI substrate. Device footprint, channel spacing scaling characteristic, crosstalk, operational bandwidth, and manufacturing complexity are compared
