Intersubband relaxation dynamics in semiconductor quantum structures
We monitor the temporal evolution of the electron population in the first and second subband of an undoped GaAs/AlGaAs asymmetric double quantum well after interband optical excitation by using an interband pump/intersubband probe technique. The spacing between the two subbands is smaller than the longitudinal optical phonon energy. We extract an intersubband lifetime of T21 = 100 ps and a reco...
متن کاملQuantum transport calculations for quantum cascade laser structures
We apply a quantum transport theory based on nonequilibrium Green’s functions to quantum cascade laser (QCL) structures, treating simultaneously the transmission through the injector regions and the relaxation due to scattering in the active region. The quantum kinetic equations are solved self-consistently using self-energies for interface roughness and phonon scattering processes within the s...
متن کاملElectron transport process in quantum cascade intersubband semiconductor lasers
Detailed self-consistent calculations have been performed of the electron transport and capture aspects of the dynamics of electrically pumped quantum cascade intersubband semiconductor lasers. Specific attention is given to the dependence of the characteristic carrier relaxation times on carrier temperature and density at different applied biases. We have found that the capture and intersubban...
متن کاملQuantum dot cascade laser
UNLABELLED We demonstrated an unambiguous quantum dot cascade laser based on InGaAs/GaAs/InAs/InAlAs heterostructure by making use of self-assembled quantum dots in the Stranski-Krastanow growth mode and two-step strain compensation active region design. The prototype generates stimulated emission at λ ~ 6.15 μm and a broad electroluminescence band with full width at half maximum over 3 μm. The...
متن کاملQuantum cascade laser technology
In the mid-infrared spectral region, where continuous wave room temperature operation of the QCL devices was achieved in the previous phase of the program, the main goal will be to further broaden the frequency range over which these high performances are achieved. Another important topic is the fabrication of devices with a very large frequency tuning capability, which will enable the spectros...
