Abstract

The ionization coefficients in Al_0.7In_0.3AsSb lattice matched to GaSb have been systematically measured over a wide range of avalanching widths. When combined with Al_0.3In_0.7AsSb as an absorber, we can show detection up to 2μ m at room temperature with low excess noise. Such avalanche photodiodes are very promising for extended short-wave infrared (eSWIR) applications such as LiDAR.
