Abstract

Silicon reflection-type arrayed-waveguide gratings (AWGs) consisting of all straight array waveguides are experimentally demonstrated for the first time to our knowledge. The AWG has 14 output channels with 400 GHz channel spacing and a footprint of 230μm×530μm. The minimum on-chip loss of 3.0 dB and crosstalk of 20dB are achieved by using a second-order distributed Bragg reflector facet.
