    摘要: A V-channeled substrate inner stripe (VSIS) laser is manufactured on a GaAs substrate. The VSIS laser includes p-Ga.sub.0.7 Al.sub.0.3 As active layer, and an n-Ga.sub.0.85 Al.sub.0.15 As cap layer. The GaAs substrate is removed from the final device. The n-Ga.sub.0.85 Al.sub.0.15 As cap layer functions to support the final device, and to minimize a stress applied to the p-Ga.sub.0.7 Al.sub.0.3 As active layer.

    摘要: A window VSIS semiconductor laser includes a stimulated region and window regions formed on both ends of the stimulated region. A V-shaped groove is formed in a substrate, and an active layer is formed on the substrate. In one preferred form, the V-shaped groove has a wider width in the stimulated region as compared with the V-shaped groove formed in the window regions. The active layer is a crescent active layer in the stimulated region. One edge of the V-shaped groove in the stimulated region is continuously aligned on a line to the corresponding edge of the V-shaped groove formed in the window regions so as to enhance the optical coupling. In another preferred form, indents are formed in the substrate in the window regions in a manner to sandwich the V-shaped groove formed in the window regions. The V-shaped groove has the same width in the stimulated region and in the window regions. The active layer is plane shaped in the stimulated region, and a thickness of the active layer in the stimulated region is thicker than the active layer formed in the window regions.

    摘要: A window V-channeled substrate inner stripe semiconductor laser which includes window regions formed at both ends of a stimulated region. The stimulated region includes a crescent active layer, and each of the window regions includes a plane active layer for transferring the laser beam emitted from the stimulated region to the mirror. The window regions ensure a stable operation of the laser oscillation and a high optical power for catastrophic optical damage.
