  • Abstract
    An Si wire array waveguide grating wavelength demultiplexer fabricated using immersion ArF lithography is reported. The tilt directions of the input and output star couplers are aligned in the same direction to avoid phase error generated at the curved waveguides. A 16 channel device with 200 GHz wavelength spacing was fabricated.
