40-Gbitys cascadable all-optical logic with an ultrafast nonlinear interferometer.
We demonstrate 40-Gbitys 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-Gbitys results of OR and NOR gating are presented.
