ABSTRACT:
A semiconductor light-emitting device includes a pair of clad layers and an active layer sandwiched thereby which together are disposed between a substrate and a cap layer so as to form a monolithic array of double-heterojunction regions each including therein a plurality of light-emitting portions of the active layer for emitting light from the end face thereof so that the light-emitting portions are arrayed in a row and electrically separated from each other. The substrate is formed at one side thereof with a concave and convex configuration following a stripe pattern so that the clad layers, active layers and the cap layers are each arranged in the form of a corrugated configuration following the concave and convex configuration of the substrate. According to the corrugated configuration of the active layer between said clad layers, one of the clad layers has portions which are each disposed between respective two successive light-emitting portions of the active layer along an array line thereof, so that when at least two successive light-emitting portions are activated to emit light, these successive light-emitting portions are also photo-coupled to each other through the corresponding portion of the clad layer disposed therebetween.
