Heterostructure injection lasers in which the GaAs active region is the center layer of a five‐layer dielectric slab waveguide have been investigated. The GaAs active layer is bounded on each side by an AlxGa1−xAs layer to confine the carriers. T

The pulsations in the laser emission from several lasers have been studied as a function of temperature, cavity length, external mirror illumination, and effect of mirror etching. Selected DH lasers with 12‐μm‐wide stripes delineated by proton b

We demonstrate that reduced reflectivity facet coatings of Al2O3 on both mirrors can increase the output power levels at which ’’kinks’’ in the light‐current characteristics of proton‐delineated 12‐μm stripe‐geometry (Al,Ga)As lasers

Recent work indicates that the alloy (Si2)x(GaAs)1−x can be formed within the GaAs quantum well of an AlxGa1−xAs-GaAs quantum well heterostructure (QWH) and results in a shift of laser operation to higher energy. In this paper we show, by SIMS an

A theory of interaction among the longitudinal modes in a laser made of highly dispersive material is outlined and used to interpret a spontaneous pulsing of the laser intensity at a frequency two orders of magnitude lower than the mode separation, s

We demonstrate that half‐wavelength facet coatings of Al2O3 can arrest the growth of pulsations in the output intensity of (Al,Ga)As double‐heterostructure lasers during cw aging in a 70 °C dry nitrogen ambient while also eliminating an initial

The time decay of the room‐temperature photoluminescence from the n=1 transition in a multiple quantum well structure grown by metalorganic chemical vapor deposition is observed to depend strongly on excitation energy density. For low excitation (0

Double heterostructure GaAs junction lasers have been operated continuously at temperatures up to 355°K by use of the advantageous thermal properties of the stripe‐geometry configuration. Spatial and spectral characteristics of the modes of these
