A photonic integrated circuit capable of 1×100 switching is reported. The switch, incorporating more than 250 photonic components along with numerous passive waveguides and bends, demonstrates power penalty <; 1 dB at 10 Gbps and extinction ratio > 50 dB.
Broadband and high-speed monolithically integrated InP 1×16 switches are developed using optical phased-array structure. Application to 160-Gbps packet switching and large-capacity variable optical buffering are demonstrated.
Using newly developed PLZT-based OBS core node, low-loss Ether-frame transmission with application-layer connectivity is demonstrated over 92-km 2-hop field testbed. Recent progresses in developing OPS/OCS hybrid router are also reviewed.
