摘要	PURPOSE:To obtain a laser having small inner distortion and high reliability by burying both sides of a mesa stripelike clad layer with ZnSSe layer lattice- matched to a mesa stripelike AlGaInP active layer. CONSTITUTION:A sandwich type double hetero junction semiconductor light emitting element in which GaInP or AlGaInP formed on a GaAs board 1 is formed as an active layer 3, and the layer 3 is interposed between clad layers 2 and 10 having larger energy band gap than that of the layer 3, smaller refractive index than that of the layer 3 and containing at least AlGaInP or AlInP is provided. The layer 10 of the side different from the side of the board 1 is formed in a mesa stripe state, and both sides of the clad layer 10 are buried with a ZnSSe layer 13 lattice-matched to the mesa stripelike AlGaInP or AlInP clad layer or the GaInP or AlGaInP active layer 3 to form an index guide type structure. Thus, a semiconductor laser having small distortion therein and high reliability can be obtained.
其他摘要	目的：通过掩埋台面条状包层的两侧，使ZnSSe层晶格匹配到台面条状AlGaInP有源层，获得具有小内部畸变和高可靠性的激光器。组成：夹层型双异质结半导体发光元件，其中形成在GaAs板1上的GaInP或AlGaInP形成为有源层3，并且层3插入在具有比其更大的能带隙的包层2和10之间。在图3中，提供了比层3的折射率小并且至少包含AlGaInP或AlInP的层3的折射率。不同于板1侧面的层10以台面条状形成，并且包层10的两侧埋有与台面条状AlGaInP或AlInP包层晶格匹配的ZnSSe层13或GaInP或AlGaInP有源层3形成折射率引导型结构。因此，可以获得其中具有小失真和高可靠性的半导体激光器。
