Hundred gigahertz spacing Si arrayed-waveguide grating using rib-waveguide multimode interference coupler at slab–array interface

Silicon arrayed-waveguide grating using rib-waveguide multimode interference coupler at the array and slab waveguide interface is reported. A 100 GHz channel spacing 8ch device showing 2.8 dB insertion loss is obtained. The insertion loss was improved compared with a device using simple width taper.

Summary:Silicon arrayed-waveguide grating using rib-waveguide multimode interference coupler at the array and slab waveguide interface is reported. A 100 GHz channel spacing 8ch device showing 2.8 dB insertion loss is obtained. The insertion loss was improved compared with a device using simple width taper.
