All-optical XOR gate using polarization rotation in single highly nonlinear fiber

We demonstrate a 10-Gb/s all-optical XOR gate based on polarization rotation induced by Kerr effect in a single highly nonlinear fiber (HNLF). Using 2 km of HNLF with a nonlinear coefficient of 9.1 W/sup -1//spl middot/km/sup -1/, we obtain a 25-dB extinction ratio at the XOR output.
