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

Remote epitaxy represents a promising method for the synthesis of thin films on lattice-mismatched substrates, but its atomic-scale mechanisms are still unclear. Here, the authors demonstrate the growth of exfoliatable GaSb films on graphene-terminat

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

Three types of GaAsP metamorphic buffer layers, including linearly graded, step graded, and metamorphic superlattices, were compared for the purposes of virtual substrates for red laser diode heterostructures. Laser diodes were fabricated on GaAs sub

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
