Carrier Lifetime and Recombination in Long-Wavelength Quantum-Well Lasers
We present a novel analysis for correcting the measured differential carrier lifetime to account for carrier population in both the barrier and separate confinement heterostructure (SCH) regions of quantum-well (QW) lasers. This analysis uses information obtained from the measured spontaneous emission spectra to correct the measured lifetime and obtain the intrinsic well lifetime. Once the intr...
متن کاملAuger 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...
متن کاملHow 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...
متن کاملAuger 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...
متن کاملTheoretical study of Auger recombination in a GaInNAs 1.3 mm quantum well laser structure
We present a theoretical study of Auger recombination processes in a GaInNAs/GaAs quantum well structure designed for 1.3 mm laser emission. The calculations are based on a 10310 k"p model, incorporating valence, conduction, and nitrogen-induced bands. The Auger transition matrix elements are calculated explicitly, without introducing any further approximations into the Hamiltonian used. We con...
