  • Abstract
    A molecular beam epitaxy grown GaInAsSb pin photodetector lattice matched to a GaSb substrate is reported. The mesa type detector has high responsivity in the 1.4 to 2.4 μm wavelength range with -0.3 V bias, 40 μA dark current for a 1 mm diameter detector and the highest detectivity D* of 2.6×1010 cm·Hz1/2/W reported for a GaInAsSb detector. The measured responsivity compares well with k·p calculations
