    摘要: A V-channel inner stripe semiconductor laser device comprising a multi-layered growth crystal having an active layer for laser oscillation but no substrate, with a buffer layer formed on the multi-layered growth crystal thicker than all of the layers of the growth crystal, where the multi-layered growth crystal and buffer layer are sandwiched between an n-sided electrode and a p-sided electrode, wherein a pair of mesa-striped channels are formed outside of the V-channel to remove the outside of the optical waveguide formed in the active layer corresponding to the V-channel.

    摘要: Light-emitting elements are divided into chromaticity groups on the basis of their chromaticity. In a planar light source, light-emitting elements selected from two of the chromaticity groups are alternately provided in a longitudinal direction and in a transverse direction, respectively. The two chromaticity groups are substantially equally away from a target chromaticity in directions reverse to each other. Further, pairs of two of the light-emitting elements belonging to the two chromaticity groups which are separated from each other, are provided so that distances d2 at which two of the light-emitting elements in each of the pairs are provided are less than distances d1 at which the pairs are provided.

    摘要: A light confinement layer constructed of a semiconductor that has a refractive index different from that of p-type second cladding layers is formed to a small film thickness of not greater than 2 μm (about 0.5 μm) on the whole surface of ridge portions of two semiconductor lasers. Thus, the light confinement layer on the ridge portions is made roughly flat so as to be easily removable by etching. As a result, the exposure of p-type second cladding layers of the ridge portions due to deep etching is prevented to allow the confinement of light into the p-type cladding layers to be stably effected. A dielectric film is formed on the light confinement layer and reinforces the current constriction function lost by the reduction in the thickness of the light confinement layer.

    摘要: An AlGaAs-based semiconductor laser 29 is formed on an n-type GaAs substrate 21 and thereafter etching is carried out until reaching an n-type AlGaAs clad layer 23 from the surface. Next, the n-type AlGaAs clad layer 23 is removed by etching with an etchant having selectivity to GaAs. Subsequently, the surface of an n-type GaAs buffer layer 22 is lightly etched. Thus, the n-type GaAs buffer layer 22 of the AlGaAs-based semiconductor laser 29 is left in a slightly abraded state on the n-type GaAs substrate 21, maintaining the flatness of the groundwork layer during growing an AlGaInP-based semiconductor laser 38 at the second time. Therefore, the flatness of the crystals of, in particular, an active layer grown at the second time can be improved, and the poor characteristics of the AlGaInP-based semiconductor laser 38 attributed to the poor flatness of the groundwork can be improved.
