Abstract

A 640×512 pixel, long-wavelength cutoff, narrow-band (Δλ/λ~10%) quantum well infrared photodetector (QWIP) focal plane array (FPA), a four-band QWIP FPA in the 4-15 μm spectral region, and a broad-band (Δλ/λ~42%) QWIP FPA having a 1 5.4 μm cutoff have been demonstrated. In this paper, we discuss the electrical and optical characterization of these FPAs. and their performance. In addition, we discuss the development of a very sensitive (NEDT-10.6 mK) 640×512 pixel thermal imaging camera having a 9 μm cutoff.
