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...

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...

Cooperative recombination of a quantized high-density electron-hole plasma in semiconductor quantum wells.

We investigate photoluminescence from a high-density electron-hole plasma in semiconductor quantum wells created via intense femtosecond excitation in a strong perpendicular magnetic field, a fully quantized and tunable system. At a critical magnetic field strength and excitation fluence, we observe a clear transition in the band-edge photoluminescence from omnidirectional output to a randomly ...
