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).
我们展示了一种紧凑的16通道200 GHz偏振分集波长解复用器电路，该电路使用了两个硅阵列波导光栅（AWG）和二维光栅耦合器。估计的光纤到光纤损耗优于-15.0 dB。由AWG引起的插入损耗和串扰分别为-2.6 dB和21.5 dB。最大偏振相关波长偏移为0.12 nm。在16个通道上，偏振相关损耗在0.06 dB至2.32 dB之间变化。整个电路占地面积为1400×850μm²。
