An ultra-low dark current normal incidence p-type strained-layer In0.3Ga0.7As/In0.52Al0.48As quantum well IR photodetector (PSL-QWIP) grown on semi-insulating (100) InP substrate by MBE technique has been demonstrated for the first time. This PSL-QWI

We present a 1.54 μm, 77 K, pulsed GaSb quantum well (QW) laser diode grown monolithically on a Si(100)-5° substrate. The III-Sb device is grown on an AlSb nucleation layer on Si with the 13% mismatch accommodated by a self-assembled 2D array of pu

We have proposed a new physical approach for the design of mid-IR lasers operating at λ = 3.2 - 3.26 μm based on type II heterojunctions with a large asymmetric band-offset at the interface (ΔE C > 0.6 eV and ΔE V > 0.35 eV). These high potential

Recent progress towards the realization of high-power, non- cryogenic (quasi-)cw mid-IR lasers based on the `W' configuration of the active region is reported. Type-II diodes with AlGaAsSb broadened-waveguide separate confinement regions are the firs

In order to tune the wavelength of lattice-matched QWIP detectors over the range from 4 - 20 microns, new designs are demonstrated for the first time which combine InGaAlAs and InGaAsP layers lattice-matched to InP and grown by gas-source molecular b

Highly p-doped silicon/silicon-germanium (Si/SiGe) quantum well (QW) structures have been grown by molecular beam epitaxy (MBE) on Si substrates for mid-infrared (3(mu) - 5(mu) ; 8(mu) - 12(mu) ) detection. These detectors operate at 77 K and are bas

Quantum Dot laser diodes have been made using InAs self- assembled quantum dots (QDs) in the active region of separate confinement heterostructures. The lasers grown by Molecular Beam Epitaxy (MBE) with stacked InAs QDs grown on GaAs gave record low

A very high performance two-stack, two-color, high strain (HS- ) quantum well infrared photodetector (QWIP) has been demonstrated. The sample was grown on a semi-insulating (100) GaAs by molecular beam epitaxy (MBE). It consists of two stacks of MWIR

Highly p-doped Si1-xGex quantum well (QW) layers have been grown by molecular beam epitaxy (MBE) on silicon (Si) for detectors in the mid-infrared regime (3 (mu) - 5 (mu) , 8 (mu) - 12 (mu) ). The 5 nm - 10 nm thick SiGe QW layers were boron doped up
