  text: We demonstrate an optical switch design that can scale up to a thousand ports
    with high per-port bandwidth (25 Gbps+) and low switching latency (40 ns). Our
    design uses a broadcast and select architecture, based on a passive star coupler
    and fast tunable transceivers. In addition we employ time division multiplexing
    to achieve very low switching latency. Our demo shows the feasibility of the switch
    data plane using a small testbed, comprising two transmitters and a receiver,
    connected through a star coupler.
