Abstract: A method for forming an electrooptic XOR logic device using an semiconductor optical amplifier is provided to form an electrooptic XOR logic device by using a characteristic of an inverter of an semiconductor optical amplifier. Characteristics of inverters of semiconductor optical amplifiers(SOA1,SOA2) are controlled by current, incident irradiation signals, and pump signals applied to the semiconductor optical amplifiers(SOA1,SOA2). The characteristics of inverters of semiconductor optical amplifiers(SOA1,SOA2) are obtained by increasing the amount of current, inputting the irradiation signals, and changing intensity of the pump signals. In the first semiconductor optical amplifiers(SOA1), B signal becomes the pump signal and A signal becomes the irradiation signal. In the second semiconductor optical amplifiers(SOA2), A signal becomes the pump signal and B signal becomes the irradiation signal. An XOR logic device is formed by adding two output signals of the semiconductor optical amplifiers(SOA1,SOA2). In the XOR logic device, the output signal has logic 1 if any one of A signal and B signal is logic 1 and the output signal has logic 0 if A signal and B signal have the same logic level.

CONSTITUTION: A pulse signal having 400ps interval is created using a fiber ring laser(10) and a pulse generator(14). A coupler inputs and divides the pulse signal. An optical delay(20a) delays one portion of the divided pulse signal. A coupler combines the delayed signal with other divided portion and makes 'A' signal having 1100 pattern. An optical delay(20b) delays the 'A' signal and makes 'B' signal having 0110 pattern. The first semiconductor optical amplifier(SOA1) inputs the 'A' signal as a probe signal, inputs the 'B' signal as a pump signal, and outputs a logic signal. The second semiconductor optical amplifier(SOA2) inputs the 'A' signal as a pump signal, inputs the 'B' signal as a probe signal, and outputs a logic signal. An XPM wavelength converter(28) inputs the 'A' signal and the 'B' signal simultaneously and outputs a logic signal having 0100 pattern.
