Paper Abstract

The MBT quantum-well detector is a new generation of detector materials and technology. Quantum-well detectors are based on mature GaAs materials growth and processing technologies that feature large wafers and outstanding material uniformity. These attributes combine to produce an affordable long wave infrared (LWIR) focal plane array (FPA). MBT quantum-well FPAs have demonstrated temporal noise equivalent temperature differences of 15 milliKelvin and operability in excess of 99.5%. The MBT detector can be bandgap engineered for peak spectral response between 3 micrometers and 19 micrometers and bandwidths from less than 0.5 micrometers to more than 4 micrometers . The MBT quantum-well detectors have been hybridized to 128 X 128 silicon multiplexers and are offered as an integrated sensor in the ImagIR, a turnkey imaging platform capable of real-time processing, display and storage of data.
