We report a hybrid silicon optical gate array based on a silicon waveguide with a III-V gain medium and two vertical grating couplers. The gates show a fast switching time, a high extinction ratio, and a positive fiber-to-fiber optical gain. The dynamic behavior of such a device is evaluated under electrically controlled gating. We further focus on a single gate performance in a packet-switched network...
We experimentally assess the performance of coherent PDM-BPSK at 40Gb/s over non-zero dispersion-shifted fiber. The BPSK-based solution is found about 7.5dB more robust than the QPSK-based solution against cross-nonlinearities induced by 10Gb/s neighbor channels.
