All-optical logic circuits based on polarization properties of nondegenerate four-wave mixing


All-optical logic circuits based on the polarization properties of nondegenerate four-wave mixing are proposed. Schemes to perform multiple triple-product logic functions are discussed, and it is shown that higher-level Boolean operations that involve several bits can be implemented without resorting to the standard two-input gates. As a simple illustration of the idea, a circuit that performs error correction on a (3, 1) Hamming code is demonstrated. Error-free performance (bit error rate of <10^(−9)) at 2.5 Gbit/s is achieved after single-error correction on the Hamming word with 50% errors.
