In this study, we introduce an automated design method for Quantum Cascade Laser (QCL) active region (AR) structure employing a generative neural network, termed an inverse network, which creates the structure designs based on specific k · p metric

Neural networks, trained with the ADAM algorithm followed by a globally convergent modification to Newton’s method, are developed to predict the threshold gain of the fundamental and first higher-order modes as functions of the refractive-index pro

The thermal conductivity of Si-doped thin films of indium phosphide grown via metalorganic vapour-phase epitaxy at different carrier concentrations and thicknesses was measured from 80 to 450 K using time domain thermoreflectance. Additionally, phono

Recently, it was shown for 4.5 μm–5.0 μm-emitting, state-of-the-art quantum cascade lasers (QCLs) that the internal efficiency can be fully accounted for when considering interface-roughness (IFR)-triggered carrier leakage from both the upper-las

Room-temperature, pulsed-operation lasing of 8.5 μm-emitting InP-based quantum cascade lasers (QCLs), with low threshold-current density and watt-level output power, is demonstrated from structures grown on (001) GaAs substrates by metal-organic che
