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 present the first prototype of a real-time bandwidth-variable coherent muxponder aggregating multiple 10GigE clients onto a symbol-rate-variable PDM-QPSK optical signal. This technology enables optical transport with power consumption linearly proportional to the actual requested traffic.
We report a hybrid silicon optical gate based on a silicon waveguide with a III–V gain medium and two vertical grating couplers. The gate shows a wide optical bandwidth, high extinction ratio with low internal noise factor and low insertion loss. We further study the gate performance under packet-switched operation.
