We demonstrate an all-optical clock and data recovery circuit for short asynchronous data packets at 10-Gb/s line rate. The technique employs a Fabry–Pérot filter and an ultrafast nonlinear interferometer (UNI) to generate the local packet clock, followed by a second UNI gate to act as decision element, performing a logical AND operation between the extracted clocks and the incoming data packets. The circuit can handle short packets arriving at time intervals as short as 1.5 ns and arbitrary phase alignment.
