optical gate switching for one signal beam using another control beam is presented in a Fabry-Perot semiconductor laser amplifier. High-speed switching, where the signal output is on without the control beam and off with it, is demonstrated employing modulation of an 800 Mbit/s pulse pattern.
We present an optical logic device which demonstrates hard-limiting of outputs and which has the potential for large fan-out and fast response. It consists of a waveguide modulator made from GaAs/AlGaAs multiple-quant...

We present an optical logic device which demonstrates hard-limiting of outputs and which has the potential for large fan-out and fast response. It consists of a waveguide modulator made from GaAs/AlGaAs multiple-quantum-well material and phototransistor, and exhibits a contrast in excess of 20.

The results of optical logic exclusive-OR (XOR) at up to 20Gbit/s in an integrated SOA-based Mach-Zehnder interferometer are presented. For the first time, to the knowledge of the authors, BER measurements are demonstrated on 10Gbit/s optical logic XOR, with zero penalty. In addition, for the first time, 20Gbit/s all-optical XOR, with an integrated device that allows simple, stable and efficient operation, is demonstrated.
