Abstract :
By using gain nonlinearity characteristics of semiconductor optical amplifier, an all-optical binary half adder at 10 Gbps is demonstrated. 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. The half adder operates in single mechanism, which is XGM.
