Abstract

By using only two input signals of A and B, an all-optical half adder that utilizes a cross gain modulation in semiconductor optical amplifiers is demonstrated at 10 Gbps. The half adder utilizes two logic functions of SUM and CARRY, which can be demonstrated by using the XOR gate and the AND gate, respectively. The extinction ratios of SUM and CARRY are approximately 6.1 dB. No additional input beam such as clock signal or continuous wave light, which is required in many other all-optical logic gates, is used in this design concept.
