Summary form only given. We have shown all-optical XOR at data rates as high as 40 Gbit/s using a novel experimental setup which allows bit error-rate testing of the pseudo-random XOR pattern at the output of the switch. To the best of our knowledge, this is the highest demonstrated rate for XOR operation on two fully-loaded pseudo-random binary streams. The folded UNI incorporating a Faraday mirror reduces polarization instabilities and provides stable performance in an all-fiber switch. Because of the high-speed nonlinear refractive index in fiber, we expect that this logic gate will readily scale to higher data rates.
