Abstract

An SU-8-based arrayed-waveguide gratings (AWG) device with multimode interference couplers (MMI) is designed and fabricated. The demonstrated MMI-AWG device has 4 channels and the channel spacing is 500GHz. The total insertion loss is about 22 dB, which mainly comes from the coupling loss (16dB) between the input/output waveguide and the fibers. The channel crosstalk between adjacent channels is about –12 dB which is close to the simulation result.
