Abstract

We demonstrate a compact 16-channel 200GHz polarization diversity wavelength de-multiplexer circuit using two silicon AWGs and 2D grating couplers. Estimated fiber to fiber loss is better than −15.0dB. Insertion loss and crosstalk induced by the AWGs are −2.6dB and 21.5dB, respectively. The maximum polarization dependent wavelength shift is0.12nm. The polarization dependent loss varies between 0.06dB and 2.32dBover the 16 channels. The total circuit footprint is 1400 ~ 850ƒÊm2 .
