Abstract: A semiconductor laser (21) has, on the surface of a layer (25) adjacent to the active layer (24), a grating (29) with such a period as to reflect light in a direction transverse to the active layer (24); in this way light is emitted from a face parallel to the layer. The laser can be coupled to an optical waveguide (11) realized in a substrate (12) on which the laser (21) can be fixed and which is provided with a grating (13) capable of rotating the radiation emitted by the laser (21) by the angle necessary for transferring the radiation into the waveguide.

Abstract: SEMICONDUCTOR LASER WITH TRANSVERSE EMISSION, AND COUPLING THEREOF TO AN OPTICAL WAVEGUIDE A semiconductor laser has, on the surface of layer adjacent the active layer, a grating with such a period as to reflect light in a direction transverse to the active layer; in this way light is emitted from a face parallel to the layer. The laser can be coupled to an optical waveguide realized in a substrate on which the laser can be fixed and which is provided with a grating capable of rotating the radiation emitted by the laser by the angle necessary for transferring the radiation into the waveguide.
