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.
