The first decade of the 21st-century has seen a rapid development in infrared photodetector
technology. At the end of the last millennium there were two dominant IR systems, InSb-and …

There has been a recent surge in interest for optical satellite communication (SatCom)
utilizing lasers. It is clear to see why, as optical SatCom is capable of higher speed, lighter …

Abstract Novel InAs/InGaAs quantum dots-in-a-well (DWELL) infrared photodetectors are
reviewed. These detectors, in which the active region consists of InAs quantum dots (QDs) …

In this letter, a longwave infrared (LWIR) InAs–InGaAs quantum dot infrared photodetector
with a peak detection wavelength of 9.9 μ m is reported. A large photoresponsivity of 2.5 A∕ …

We report experimental results showing how the noise in a Quantum-Dot Infrared
photodetector (QDIP) and Quantum Dot-in-a-well (DWELL) varies with the electric field and …

Normal incidence InAs/In 0.15 Ga 0.85 As dots-in-a-well (DWELL) detectors are reported in
which the peak operating wavelength was tailored from 7.2 to 11 μm using heterostructure …

A major obstacle in the growth of stacked dot structures with a large number of layers is the
high degree of strain in the dot layers. Strain buildup can affect the nucleation of the dots …

We demonstrate the highly promising pip InAs/GaAs quantum dots based infrared
photodetector (QDIP) which utilize intra-valence band hole transitions as against electron …

In this paper, a high operating temperature (HOT) middle wave infrared (MWIR) InAs/GaAs
quantum dot (QD) infrared photodetector (QDIP) is reported. The QDIP covers a wide …

In this paper, the basics and some of the recent developments in quantum dots-in-a-well
(DWELL) focal plane arrays (FPAs) are reviewed. Fundamentally, these detectors represent …
