Optically addressable 2 x 2 exchange/bypass packet switch

In this letter, we demonstrate an optically addressable 2 /spl times/ 2 exchange-bypass switch operating with 10-Gb/s data packets. Switching is achieved at the bit level using an ultrafast nonlinear interferometer gate with two input data signals and a single control signal. The bit error rate of the switch in a static configuration was estimated to be 10/sup -11/ using synchronous digital hierarchy 64 data frames.
