ABSTRACT
We have demonstrated quantum cascade lasers (QCL) emitting at ∼5μm based on efficient injection of the four quantum wells active region design with vertical transitions and strain-compensated superlattice with high injection efficiency and short ground state lifetime. Using a processing sequence adjusted for QCL state of the art devices were reproducibly obtained.

    The simulations of polariton relaxation and Bose condensation in GaN microcavities (both bulk and with quantum wells) are performed by solving semiclassical Boltzmann equations. A complete set of kinetic phase diagrams for the most important parameters is calculated. We show that such cavities...

    This work reports on InAs quantum wells (QWs) grown on GaAs-based metamorphic In0.83Al0.17As buffers for type-I mid-infrared (MIR) emission. X-ray diffraction and Raman measurements show that the GaAs-based quantum wells have similar lattice and strain conditions with the InP-based structure....

    High-power broad-area laser diodes often suffer from a widening of the slow-axis far-field with increasing current (lateral far-field blooming). This effect is commonly attributed to self-heating. Utilizing self-consistent electro-thermal-optical simulations, we analyze previous experimental...

    The optical properties of InGaAsN QW grown on AlGaAs/GaAs cladding layers were investigated. Al contamination in the quantum well due to the memory effect is responsible for the degradation of optical quality. We propose a growth method to reduce the Al contamination by growth interruption and...
