16-Channel 100 GHz-spaced integrated polarization diversity silicon-based slot-blocker for high data rate reconfigurable networks

We report on a fully integrated 16-channel polarization diversity fast slot-blocker with 100 GHz channel spacing using silicon photonics. We demonstrated extinction ratio of 20 dB and switching time of 10 ns timescale allowing add-drop operation as high as 320 Gbit/s PDM-32QAM signals.
