Abstract

We propose a novel one-level simplification method for all-optical combinational logic circuits. With the proposed method, an all-optical gray code to binary coded decimal converter is successfully developed for the first time by using conventional semiconductor optical amplifiers as building elements. In comparison to the construction algorithm based on the conventional two-level simplification method, a significant improvement is observed in the Q-factor.
