Auger Recombination in Quantum - Well InGaAsP Heterostructure Lasers

Interband nonradiative Auger recombination in quantumwell InGaAsP/InP heterostructure lasers has been calculated. It is found that the Auger rate is much reduced in the quasi two-dimensional quantum-well lasers. This suggests that the temperature sensitivity of quantum-well InGaAsP lasers is much less than ordinary structures with much higher values of To at around room temperatures. A CONTINUI...

Auger Recombination Processes and Threshold Conditions in Asymmetric-Multiple-Quantum-Well Heterostructure Lasers

Different possible processes of non-radiative Auger recombination which occur in the active region of quantum-well lasers are analyzed and the temperature dependence of the lasing threshold in the GaInAs-GaInAsP-InP bi-quantum-well heterolasers with different widths of the quantum wells (4 and 9 nm) is determined. Activated behavior of the Auger recombination is mentioned and respective effecti...

How to restrain Auger recombination predominance in the threshold of asymmetric bi-quantum-well lasers

Both radiative and nonradiative processes which occur in the active region of GaInAs–GaInAsP–InP asymmetric multiple quantum-well (AMQW) heterolasers with two quantum wells of different width (4 and 9 nm) are described. Several possible processes of non-radiative Auger recombination which affect the temperature sensitivity of the lasing threshold are analyzed and the temperature dependencies of...

Characterization of mid-infrared quantum cascade lasers

Quantum cascade lasers provide some of the highest output powers available for light in the mid-infrared range (from 3 to 8 μm). As many of their applications require portability, designs that have a high wall-plug efficiency are essential, and were designed and grown by others to achieve this goal. However, because a large fraction of these devices did not operate at all, very few of the stand...
