An Ultra-Fast All-Optical Error Detection and Correction Circuit Based on Spectral Logic

Abstract

All-optical logic circuits based on the polarization properties of non-degenerate four-wave mixing are proposed. It is shown that higher-level Boolean operations involving several bits can be implemented without resorting to the standard 2-input gates. As a simple illustration of the idea, a circuit performing error correction on a (3, 1) Hamming Code is demonstrated. Error-free performance (Bit Error Rate of < 10(exp -9) at 2.5 Gbit/s is achieved after single-error correction on the Hamming word with 50 percent errors.
