Abstract

We experimentally demonstrate a 8×8, 200 GHz cyclic AWG router using silicon oxynitride waveguides. The relative refractive index difference between the core and cladding layers is 9.75%. The output spectral response when light of TM polarization is input from the central input channel shows the central channel loss, non-uniformity and crosstalk are -1.51 dB, 2.23 dB, and -19 dB, respectively. And when light is input from the edge input channel, the central channel loss, non-uniformity and crosstalk are -3.68 dB, 2.38 dB, and -19 dB, respectively. Crosstalks vary from -19 dB to -21 dB for all channels. The device is polarization sensitive and a polarization dependent wavelength shift occurs in the spectral response of each output channel. The central wavelengths from central input channel to central output channel for the TE and TM polarization are 1553.8 nm and 1550.2 nm.
