摘要：

We report an all-optical multiple-channel exclusive OR (XOR) gate for 10 Gbits/s non-return-to-zero differential phase-shift keying ( NRZ-DPSK) signals using nondegenerate four-wave mixing in a silicon waveguide. The function of the logic XOR gate is experimentally demonstrated using 40 bit DPSK sequences. Also, the eye diagram of the XOR signal is clearly observed as the incident signals are both modulated by DPSK sequences originating from 2(31)-1 pseudorandom binary sequences.
