Fast photoconductive detector using p-In0.53Ga0.47As with response to 1.7 μm

Abstract
Photoconductive detectors, fabricated from p‐type In0.53Ga0.47As using strip‐line techniques, exhibit rise and fall times of 45 and 70 psec FWHM. This performance is consistent with a peak electron drift velocity of 2.1×107 cm/sec at a field of ∼3.5 kV/cm and represents the fastest reported detector response for the 1.0–1.7‐μm wavelength range.
