The surface morphology of a buffer template is an important factor in the heteroepitaxial integration of optoelectronic devices with a significant lattice mismatch. In this work, InP-based long-wave infrared (~8 µm) emitting quantum cascade lasers w

We present a reverse-taper quantum cascade laser (QCL) emitting at 4.6 μm, a novel-geometry device that can scale the output power while maintaining good beam quality. Buried-ridge waveguides with tapered and straight regions were formed by ICP etch

The performances of mid-infrared (IR) quantum cascade lasers (QCLs) are now reaching a maturity level that enables a variety of applications which require compact laser sources capable of watt-range output powers with high beam quality. We review the

We present a quantum transport simulation of a 4.6- μ m quantum cascade laser (QCL) operating at high power near room temperature. The simulation is based on a rigorous density-matrix-based formalism, in which the evolution of the single-electron de

Grating-coupled, surface-emitting (GCSE) quantum-cascade lasers (QCLs) of linear geometry generally operate in an antisymmetric mode, which is undesirable due to its double-lobed far-field beam pattern. The antisymmetric mode can be suppressed by des
