Abstract :
A novel XOR logic gate using dual cascaded ultrafast nonlinear interferometer elements based on semiconductor optical amplifiers is proposed and demonstrated at 40 Gbit/s. The gate is switched at the line rate rather than twice line rate, as in previously reported differential XOR gates.
