  • Abstract
    The demonstration of D* in excess of 2×109 cmHz 1/2W-1 from 1 mm diameter, uncooled, semiconductor diode detectors with a peak wavelength response at 5 μm is reported. They are based on heterostructures in the In1-xAlxSb alloy system and employ hyperspherical optical immersion. The devices have sufficiently high impedance for convenient amplifier matching. Without signal-to-noise degradation, and the potential for high frequency response above 100 kHz
