Intervalence Band Absorption and Carrier Heating in Type-II Sb-Based Lasers

Abstract

Using a nonlinear pump-probe technique, investigations of the carrier dynamics and band structure in MIR Sb-based lasers has been conducted. Specific attention has been given to Type-II QW interband transitions. In addition, measurements of the significant carrier/lattice heating at high temperatures related to slow (approximately 100 ms) thermal diffusion times are reported. Finally, the luminescence lifetime has been found to decrease significantly with temperature showing increased carrier/lattice heating and non-radiative recombination rates.
