Abstract

The near-infrared quantum efficiency of pin photodetectors based on a lattice-matched type-II InGaAs/GaAsSb absorption region has been measured. The quantum efficiencies for these devices are 80.2 and 57.8% at 1064 and 1550 nm, respectively. These results are comparable to the more commonly-used InGaAs/InP photodetectors.
