Abstract

The demonstration of D* in excess of 2×10⁹ cm Hz^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 In_1-xAl_xSb 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.
