Abstract

We demonstrate 40-Gbit/s all-optical bitwise inversion and wavelength conversion, using an ultrafast nonlinear interferometer. This device uses optically induced gain and index nonlinearities in a semiconductor amplifier to achieve the high-rate switching. The device is cascadable and can be configured to perform a variety of switching functions. As an example, 10-Gbit/s results of or and nor gating are presented.
