摘要

We report AlInAsSb separate absorption, charge, and multiplication (SACM) avalanche photodiodes with a >3-

$\mu \text{m}$

optical cutoff, operating at 240 K. Gain and dark current performance further improve with reduced temperature. 65% external quantum efficiency at 2-

$\mu \text{m}$

is achieved without anti-reflection enhancement.
