Design and characterization of an arrayed-waveguide grating router with an interleave-chirped array

抄録

The loss uniformity of an arrayed-waveguide grating router was improved by employing an interleave-chirped arrayed-waveguide grating, without increasing the maximum loss. We fabricated a 16 × 16, 50-GHz channel-spacing, interleave-chirped arrayed-waveguide grating router for use in 1-µm wavelength band communications. The minimum loss, the maximum loss, and the loss uniformity were 5.4 dB, 7.0 dB, 1.6 dB, respectively.
