Recent progress on the hybrid optoelectronic router

We review our technologies for realizing a hybrid optoelectronic router for future optical packet-switched networks. The router optimally utilizes both optical and electrical technologies to reduce power and latency while supporting the functionality of various services (multicast, QoS, etc.). We also present recent results on router-based demonstrations, including multicast routing, TTL-based multi-hop transmission, and an interconnection experiment of two packet ring networks with the router.
