摘要： An index-guided buried heterostructure AlGalnN laser diode provides improved mode stability and low threshold current when compared to conventional ridge waveguide structures. A short period superlattice is used to allow adequate cladding layer thickness for confinement without cracking. The intensity of the light lost due to leakage is reduced by about 2 orders of magnitude with an accompanying improvement in the far-field radiation pattern when compared to conventional structures.

摘要： A method for placing nitride laser diode arrays on a thermally conducting substrate is described. The method uses an excimer laser to detach the nitride laser diode from the sapphire growth substrate after an intermediate substrate has been attached to the side opposite the sapphire substrate. A thermally conducting substrate is subsequently bonded to the side where the sapphire substrate was removed.

摘要： Methods for defect-free impurity-induced laser disordering (IILD) of AlGaInP and AlGaAs heterostructures. Phosphorus-doped or As-doped films are used in which silicon serves as a diffusion source and silicon nitride acts as a barrier for selective IILD. High-performance, index-guided (AlGa).sub.0.5 In.sub.0.5 P lasers may be fabricated with this technique, analogous to those made in the AlGaAs material system. The deposition of the diffusion source films preferably is carried out in a low pressure reactor. Also disclosed is a scheme for reducing or eliminating phosphorus overpressure during silicon diffusion into III-V semiconducting material by adding a pre-diffusion anneal step. Defects produced during intermixing are also reduced using a GaInP or GaInP/GaAs cap.

摘要： A QW diode laser generating orthogonally polarized multiple beams. The device incorporates quantum well active regions capable of, transitions to heavy hole and light hole band edges. The heavy hole transition provides TE-mode gain, while the light hole band provides mostly TM-mode gain. By controlling the compositions and thicknesses of the active regions, both modes can be obtained in a monolithic structure. In addition, the resulting laser polarization will be very sensitive to the threshold carrier density. With an intracavity loss modulator in such a structure, the polarization can also be controlled. Other ways of causing side-by-side lasers to operate, respectively, in their TE or TM modes are also described.

摘要： Ridged waveguide and selectively-buried ridged waveguide, index-guided, visible semiconductor lasers incorporating a lattice-mismatched, preferably tensile-strained, etch-stop layer in the design and fabrication of the laser. Compared with other structures with etch-stop layers that are lattice matched, the etch-stop layer of the invention would have greater etch-rate selectivity, and the resulting structure would be more optically transparent with less transverse mode distortion and would present fewer difficulties with layer regrowth. These advantages would translate into greater design flexibility, more reliable fabrication, and better device performance. A preferred material for the etch-stop layer is Ga.sub.x In.sub.1-x P (x>0.5).
