英文摘要	PURPOSE:To logically operate and process a plurality of optical signals and to output the result as the optical signals, by constituting the combination of electrical conductive and nonconductive states through the combinations of presence/absence of the optical signals in a semiconductor including a photodetecting, a light emitting and a light absorbing region. CONSTITUTION:In a semiconductor epitaxial crystal, an N-Ga1-xAlxAs layer 1, an N-Ga1-yAlyAs layer 2 and an N-Ga1zAlzAs layer 3 form a light emitting region, an N-Ga1-tAltAs layer 5, an N-Ga1-uAluAs layer 6, an N-Ga1-vAlvAs layer 7 and an N-Ga1-wAlwAs layer 8 constitute a photodetecting region and an N-GaAs layer 4 forms a photoabsorbing region. A P-region (crossed lines) 9 is formed in the layers 1, 2 with impurity diffusion and a high resistance region (oblique lines) 10 is formed to each layer through the injection of proton. An insulation film 11 and electrodes 12 are formed with SiO2. Photodetection regions X, Y are arranged in series with the high resistance region, and only when the two photodetecting regions receive an optical input signal and turn on, the light emitting region Z is conductive, allowing to operate logical product.
