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.

Abstract: PURPOSE: A method and device for implementing an electrooptic half adder using an element based on an SOA(Semiconductor Optical Amplifier) is provided to combine optical devices easily and to realize an independence of a polarized light and a wavelength by implementing an electrooptic XOR logic element using an inverter characteristic of the SOA and by implementing an electrooptic AND logic element using an XPM wavelength conversion. 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.

Abstract: PURPOSE: An apparatus for realizing an electric light OR logic element using a semiconductor optical amplifier is provided to realize the electric light OR logic element by using gain saturation and wavelength conversions characteristics. CONSTITUTION: A pulse generator(100) generates light pulses. An MLFL(Mode Locked Fiber Laser)(102) generates input signal patterns A and B of an electric light OR logic element from the pulse generator.

A first optical delay obtains time delay of the output light from the first FC through a variable delay(108) and an SMF(Single-Mode Fiber)(110). A first optical controller controls the strength and polarization of the output light of the first FC through an attenuator(112) and a polarization controller(114). A second FC(116) combines the output light of the first optical delay and the first optical controller for generating the input signal pattern A. A third FC(118) divides the output light of the second FC at a ratio of 10 to 90. A second optical delay obtains time delay of the output light from the second FC through a variable delay(120) and an SMF(122). A fourth FC(124) detects the input signal pattern B generated from the second optical delay. A second optical controller controls the strength and polarization of the output light of the third FC through an attenuator(126) and a polarization controller(128). A fifth FC(130) combines the input signal patterns A and B for generating an input signal pattern A+B. An optical detecting and measuring element detects and measures the input signal pattern A+B.
