Journal Of Applied Physics, 1 juin 1998, Volume : 83, Numéro : 11
We explore the possibility of covering the short wavelength infrared region using intersubband transitions in GaAs-based quantum wells. We investigate InGaAs...
Using GaAs based quantum well infrared photodetectors (QWIPs) with either GaAs or InGaAs wells, we experimentally investigate the accuracy of the polarization...

This report describes the concept, design and implementation of the Canadian Quantum Well Infrared Photodetector (CA QWIP) experiment on UK STRV 1D satellite....
Journal Of Applied Physics, 15 juillet 1997, Volume : 82, Numéro : 2
A systematic study of a set of GaAs/AlGaAs quantum well infrared photodetectors with various shapes of the first barrier (which acts as the device emitter or...
We present an analysis of physical effects responsible for infrared image transformation in integrated quantum well infrared photodetector-light emitting diode...
Physica E: Low-dimensional Systems and Nanostructures, avril 2000, Volume : 7, Numéro : 1-2
The effects of optical interference in quantum-well infrared photodetectors (QWIPs) caused by reflection of radiation from the metal contact are investigated....
This letter presents the recent developments of large-area focal plane "pseudo" arrays for infrared (IR) imaging. The devices are based on the epitaxial...
We propose a novel method that, for the first time to our knowledge, makes it possible to tailor the spectral response of an input grating coupler. This method...
Optimum bound-to-continuum normal-incidence absorption in low-doped (less than 1×1012cm-2) p-type GaAs/AlGaAs quantum wells obtains for well widths for which...
We present experimental results which support a recently proposed scheme for infrared imaging through the combined use of a photon frequency up-conversion...
