Abstract

This letter reports on 10-GHz and 20-GHz channel-spacing arrayed waveguide gratings (AWGs) based on InP technology. The dimensions of the AWGs are 6.8 times 8.2 mm² and 5.0 times 6.0 mm², respectively, and the devices show crosstalk levels of -12 dB for the 10-GHz and -17 dB for the 20-GHz AWG without any compensation for the phase errors in the arrayed waveguides. The root-mean-square phase errors for the center arrayed waveguides were characterized by using an optical vector network analyzer, and are 18deg for the 10-GHz AWG and 28deg for the 10-GHz AWG.
