    摘要: Diode type laser devices (diode layers) with nonabsorbing windows that are obtained in low confinement asymmetric structures, that consist of a waveguide and an active region, the action region being situated asymmetrically relative to the waveguide, at an extremity of the waveguide central layer, outside, at the margin or inside the waveguide central layer. The nonabsorbing mirrors can be obtained by the partial etching of the diode lasers layered structures, by this etching the active region being removed but in a large extent the layered structure remaining unaffected, and by the regrowth of a material with an adequate crystalline structure and nonabsorbing for the radiation emitted by the laser. By such a process the optical properties of the waveguide are reconstructed in a large extent, so that the radiation propagates to the mirror into a waveguide similar with the waveguide of the rest of the laser.

    摘要: A p-i-n structure for use in photo laser diodes is disclosed, being formed of an GaxIn1-xN/GaN alloy (Xnull0null1). In the method of the subject invention, buffer layers of GaN are grown on a substrate and then doped. The active, confinement and confinement layers of p-type material are next grown and doped, if desired. The structure is masked and etched as required to expose a surface which is annealed. A p-type surface contact is formed on this annealed surface so as to be of sufficiently low resistance as to provide good quality performance for use in a device.

    摘要: A manufacturing method of a laser diode and a laser diode array is disclosed. A current blocking layer is very thinly grown on the surface of a mesa-like structure provided in a semiconductor substrate due to certain growing characteristics when forming the current blocking layer on the surface of a semiconductor substrate. Therefore, a channel is formed by utilizing the characteristic that GaAs is etched faster than AlGaAs when melt-etched by an unsaturated melted source. A first cladding layer and epitaxial layers are subsequently formed. The channel is easily formed by melt-etching because the current blocking layer is thinly formed on the surface of a reverse mesa-like structure of the semiconductor substrate. Also, a desired operation mode is freely determinable by controlling the Al mole concentration of the current blocking layer. In manufacturing the laser diode and laser diode array, melt-etching for forming the current blocking layers is performed by one epitaxy step. Accordingly, the surface of a mesa-like structure on the substrate is protected from oxidation or defects after melt-etching, thereby improving the production yield and reliability of a given device.
