Quantum-well capture and interwell transport in semiconductor active layers

The dynamics of electrons and holes in multiquantum-well semiconductor gain media involves several different transport processes, such as diffusion and drift across the barrier region, as well as capture and escape transitions between the bound and the unbound states of the quantum wells. In addition to their fundamental interest, these processes are important because of their implications for ...

Comparison of the quantum efficiencies of interwell and intrawell radiative transitions in quantum cascade lasers

A theoretical study has been made to compare the quantum efficiencies of interwell and intrawell radiative transitions in quantum cascade lasers based on AlxGa1 xAs/GaAs technology. Radiative and non-radiative intersubband transition rates were calculated for a range of temperatures between 4 K and 300 K at an applied electric field of 4 kVcm 1 for structures designed to emit in both mid-infrar...
