This paper presents the results of a numerical analysis of nitride-based edge-emitting lasers with an InGaN/GaN active region designed for continuous wave room temperature emission of green and blue light. The main goal was to investigate whether the indium thin oxide (ITO) layer can serve as an effective optical confinement improving operation of these devices. Simulations were performed with the...
In the present paper the results of the computer analysis of the GaAs-based and GaSb-based active regions that can be applied in compact semiconductor laser sources of radiation at mid-infrared wavelengths are presented. Quantum well material contents and strain dependencies on the maximal gain are investigated. It is shown that above 3 μm the maximal gain obtained for GaInNAs/AlGaInAs active region...
In the present paper, the comprehensive fully self-consistent optical-electrical-thermal-recombination model is used to determine the optimal structure of the possible GaInNAs quantum-well (QW) tunnel-junction (TJ) vertical-cavity surface-emitting lasers (VCSELs) with single-fundamental-mode operation at 2.33 μm wavelength suited for carbon monoxide sensing applications. From among various considered...
