Abstract :
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 demonstrate subwavelength switching operations with multiformat and multibit-rate optical packet based on direct and coherent detection.
