Bit-rate flexible all-optical demultiplexing using a nonlinear optical loop mirror

The nonlinear optical loop mirror is shown to be capable of demultiplexing 20 Gbit/s pulses from a continuous 40 Gbit/s data stream. Bit error rate measurements are presented for a demultiplexed 10 Gbit/s channel, and the sensitivity of the error rate to timing jitter between the signal and clock pulses is examined. Bit-rate flexible demultiplexing can be achieved.
