Abstract
The present invention relates to a method of embodying all-optical XOR logic gate by using semiconductor optical amplifier, and more particularly, to a technique to embody all-optical XOR logic gate utilizing the cross-gain modulation (XGM) characteristic of semiconductor optical amplifiers controllable with input currents, illumination signal, and pumping signal. The method of all-optical XOR logic element in accordance with the present invention is characterized to obtain operational characteristic of the all-optical XOR logic element by inputting pump-signal and illumination signal concurrently into two semiconductor optical amplifiers and then summing the two output signals having XGM characteristic arising from gain saturation and wavelength conversion of the semiconductor optical amplifiers.
