英文摘要	We have demonstrated a two-contact quantum well infrared photodetector (qwip) exhibiting simultaneous photoresponse in both the mid- and the long-wavelength atmospheric windows of 3-5 mu m and of 8-12 mu m. the structure of the device was achieved by sequentially growing a mid-wavelength qwip part followed by a long-wavelength qwip part separated by an n-doped layer. compared with the conventional dual-band qwip device utilizing three ohmic contacts, our qwip is promising to greatly facilitate two-color focal plane array (fpa) fabrication by reducing the number of the indium bumps per pixel from three to one just like a monochromatic fpa fabrication and to increase the fpa fill factor by reducing one contact per pixel; another advantage may be that this qwip fpa boasts broadband detection capability in the two atmospheric windows while using only a monochromatic readout integrated circuit. we attributed this simultaneous broadband detection to the different distributions of the total bias voltage between the mid- and long-wavelength qwip parts.
