    摘要: A novel InP-based semiconductor laser comprises an unpatterned active region that is essentially co-extensive with the substrate of the laser, an electron stopper layer, and a separate confinement heterostructure (SCH) layer that has a portion of thickness greater than the thickness of the remainder of the SCH layer. The difference in thickness serves to provide lateral guiding of the laser mode. A patterned current blocking layer is disposed on the SCH layer, with a window in the blocking layer defining the region of increased thickness of the SCH layer. The inventive laser is readily manufacturable and can have improved properties.

    摘要: The specification describes an improved form of heterostructure laser, termed a "Rib-Loc" laser. It is an easily fabricated device with desirable electrical and optical properties. The Rib-Loc is simple to fabricate because a single, self-aligned rib provides ohmic contact, current confinement and lateral waveguiding. A deeply etched P-cladding layer outside the rib provides the positive index change needed for an index-guided laser. The large optical cavity increases the maximum power output and reduces the aspect ratio of the beam.

    摘要: In LPE boat-slider apparatus the boat, which carries the melts, is made of lower thermal conductivity material than the slider, which carries the substrate. Illustratively, the boat comprises sapphire and the slider comprises graphite. A confined-melt geometry is also described in which another slider, used to skim off thin portions of the melt, is also made of the lower thermal conductivity material.

    摘要: The present invention provides a method for monolithic integration of multiple devices on an optoelectronic substrate. The method, in a preferred embodiment, includes forming an active layer having a given wavelength over a substrate. The method further includes forming an N-type doped layer over a portion of the active layer to form first and second active regions within the active layer, the first active region having the given wavelength and the second active region having an altered wavelength different from the given wavelength. In one exemplary embodiment, the conditions used to form the N-type doped layer, for example, dopant concentration, growth rate and temperature, cause the difference in wavelength between the given wavelength and the altered wavelength.
