Abstract

We present experimental results on how the polarization properties of non-degenerate four-wave mixing can be used in advanced all-optical logic gates. The technique enables 3-bit logic operations without cascading nonlinear elements. These gates may be suitable for logic operations in an opto-electrical front-end, which moves some of the necessary computation of data to the optical domain, both after transmission and before detection. A 3-bit ADDER is demonstrated, and scalability to circuits with more inputs are discussed.
