Abstract:
We demonstrate a compact 16-channel 200 GHz polarization diversity wavelength de-multiplexer circuit using two silicon AWGs and 2D grating couplers. Estimated fiber to fiber loss is better than -15.0 dB. Insertion loss and crosstalk induced by the AWGs are -2.6 dB and 21.5 dB, respectively. The maximum polarization dependent wavelength shift is 0.12 nm. The polarization dependent loss varies between 0.06 dB and 2.32 dB over the 16 channels. The total circuit footprint is 1400 × 850 μm(2).
