Demonstration of 20 Gbit/s all-optical logic XOR in integrated SOA-based interferometric wavelength converter

摘要

The results of optical logic exclusive-OR (XOR) at up to 20 Gbit/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 10 Gbit/s optical logic XOR, with zero penalty. In addition. For the first time 20 Gbit/s all-optical XOR, with an integrated device that allows simple, stable, and efficient operation, is demonstrated.
