Abstract

We demonstrate compact 12-channel 400 GHz arrayed waveguide grating wavelength demultiplexers (AWG) in
silicon with a flattened spectral response. Insertion loss, crosstalk and non-uniformity are −3.29dB , 17.0dB and 1.55dB respectively. The flattened spectral response is obtained by using an optimized mode shaper consisting of a multi-mode interference coupler as the input aperture of the AWG. The ratio of the 1dB bandwidth to the 10dB bandwidth is improved by 50%, from 0.33 to 0.49 compared to a conventional AWG. The device size is only 560 ~ 350ƒÊm2 .
