100-Gbit/s bitwise logic

We demonstrate 100-Gbit/s bitwise logic in an all-optical semiconductor optical amplifier-based switching device, the ultrafast nonlinear interferometer. To the best of our knowledge this is the first demonstration of 100-Gbit/s AND and INVERT functionality with a 100-GHz optical clock stream and a 100-Gbit/s data stream as the logical inputs to a semiconductor-based switch. Additionally, 100-Gbit/s inverting and noninverting all-optical wavelength conversion are demonstrated.
