Monolithic integrated reflective polarization diversity SOI-based slot-blocker for fast reconfigurable 128 Gb/s and 256 Gb/s optical networks

We demonstrate a novel fully integrated, silicon-on-insulator, 16-channel polarization diversity fast reflective slot-blocker with nanosecond switching time, integrating more than 65 functional elements. Its suitability for use in reconfigurable metropolitan networks is assessed.
