We demonstrate an all-optical clock recovery circuit for operation with short data packets of 10-Gb/s rate. The circuit uses a Fabry-Pérot etalon and a nonlinear UNI gate and is capable of acquiring the clock signal within a few bits. Index Terms-All-optical clock recovery, Fabry-Pérot filter, optical packet switched networks, semiconductor optical amplifier, ultrafast nonlinear interferometer.
