Abstract
PURPOSE:To emit large optical output in one direction by mounting the light- emitting element in gallium nitride covered with a film opaque to luminescence on the surface at the substrate side. CONSTITUTION:When positive voltage is applied to a lead 5 and negative voltage to a lead 6, luminsecence is generated in a region in a thin-film 2 in gallium nitride contacting with a light-emitting electrode 3, and the light 8 is emitted through the transpacent sapphire substrate 1. Since the surface 1' of the substrate 1 is covered with the opaque film 10 here, the light generated in the light-emitting region is not emitted from the substrate 1' side, and the light 8 is emitted from a side surface 11, an area thereof is by far small. Accordingly, optical input to an optical fiber can be made extremely larger than normal elements when the optical fiber is bonded to one side surface of the element.
