英文摘要	PURPOSE:To obtain an optical IC, light-receiving efficiency thereof does not alter due to a temperature change and which has high reliability, by integrally forming a semiconductor laser element and a light-receiving element in one chip through the same method as a conventional laser element preparation and simplifying the mounting of the elements. CONSTITUTION:An N-InP buffer layer 2, an N-InGaP waveguide 3, an N-InP isolation layer 4, an N-InGaAsP active layer 5, a P-InP clad 6 and a P-InGaAsP connecting layer 7 are formed onto an N-InP substrate 1 in an epitaxial manner, grooves 11 in approximately 3mum width are shaped through etching up to the isolation layer 4 at intervals of 20mum, and a laser section 13 and a light-receiving section 14 are formed. A window is bored onto the layer 7 and an ohmic electrode 9 consisting of an Au-Zn alloy is attached, and an Au-Sn ohmic electrode 10 is stuck onto the back of the substrate When forward currents are flowed through the laser 13, short resonator lasers 12 equally oscillate, mutually couple and make progress in the waveguide 3, and are absorbed by the light-receiving section 14 and are changed into photocurrents. In said constitution, a light-receiving element for monitoring needs not be manufactured separately, mounting is simplified, and light-receiving efficiency does not vary due to a tem perature change.
