“…Broadband QWIP structures have been widely investigated by several groups [9][10][11][12][13][14]. Solutions based on conventional quantum wells [9,13,14], graded superlattice barriers [10], and superlattices instead of uncoupled quantum wells [11] have been proposed.…”

“…Solutions based on conventional quantum wells [9,13,14], graded superlattice barriers [10], and superlattices instead of uncoupled quantum wells [11] have been proposed. The dependence of the broad spectral shape on the applied bias has been studied and solutions for bias insensitive FWHM emerged [13].…”

“…It is well known that due to the presence of an injection barrier the electric field is stronger close to the emitter. Moreover, a simple analysis based on the fact that quantum wells with different activation energies also have quite different impedances [12,14] leads to the hypothesis that at high temperature the electric field should exhibit a staircase-like distribution.

“…Large-format FPAs (>640 Â 512) in the very long wavelength region of the thermal infrared spectrum (11)(12)(13)(14)(15) lm) with very high radiometric and imaging performance are of increasing scientific and operational interest for, e.g., meteorology and atmospheric chemistry, Earth Observation missions (Landsat, Meteosat Third Generation, Post-Eumetsat Polar System) or Planetary Science missions. Due to very stringent system requirements, the targeted performance levels can only be achieved with photon detectors with appropriate cooling ((77 K).…”

“…Recently the European Space Agency (ESA) has chosen a consortium led by the III-V Lab to develop enhanced broadband (11)(12)(13)(14)(15) lm) QWIP focal plane arrays for spectro-imaging applications: Dispersive Spectrometers (DS) and Fourier Transform Spectrometers (FTS). An exhaustive description of the project and of the retained development approach is given in Ref.…”
