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 FC(Fiber Combiner)(106) divides output light of the MLFL at a ratio of 50 to 50 through an optical isolator(104). 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.
