The fiber Fabry-Perot tunable filter works fast enough (three orders of magnitude faster than commercially available filters) to allow packet switching to be implemented on an all-optical wavelength-division-multiplexed packet-switched network.

The system uses a broadcast-and-select design, when each node transmits at a Gb/s on a dedicated wavelength and tuning at the receiver in performed in microseconds, as opposed to milliseconds for an earlier design. Another challenge of optical packet switching is fast clock-recovery and synchronization of the packets. We have developed a system that uses a surface acoustic wave filter. It recovers clock as fast as in several hundred bits.
