Abstract

PURPOSE:To obtain a light-receiving element consisting of a light waveguide and a light detector, both of them being united, by a method wherein on a semiconductor layer of one conductivity type, a layer of the same conductivity type and having an energy gap smaller than the semiconductor layer mentioned above is formed, the grading of the wave length to be divided is applied on the surface of the layer, and a region of the reverse conductivity type is formed on the whole or a part of the back side of the semiconductor layer. CONSTITUTION:On an n type In0.53Ga0.47As substrate 21 having an energy gap of 0.75eV. an n type 1nP layer 22 of 1.02 eV energey gap is grown and on the layer 22, an n type 1n0.78Ga0.22As0.52P0.48 layer 23 having a 1.02eV gap smaller than the gap of the layer 22 is grown, and on the layer 23 a plurality of gratings 24 having various grating wave length are formed. On the whole surface or the place directly beneath the gratings 24 respectively of the substrate 21, a plurality of p type 1n0.53 Ga0.47As layer 25 are formed by diffusion, and p type electrodes 26 are attached. To the substrate 21, n type electrodes 27 are attached.
