摘要：

We report an all-optical module that performs simultaneous header separation and reinsertion in 10-Gbit/s short optical packets of variable payload length and that consists of two subunits. The first uses a Fabry-Perot filter and an ultrafast nonlinear interferometer (UNI) to perform packet clock recovery. The second is a UNI gate configured as a 2 X 2 exchange bypass switch that is optically controlled by the recovered clock packets. Using fixed delays, the data packets and the locally generated headers are fed into the 2 X 2 switch, where header replacement is achieved.
