Avalanche photodiodes (APDs) are the detector of choice for low noise, high speed, high sensitivity photodetectors. Applications in the mid-IR (3-5 micron) include optical trace gas detection, LADAR, quantum cryptography and targeting countermeasures. Currently there are no commercially available APDs operating in this wavelength range. To address this need, this Phase I program will investigate using the III-V ternary alloy InAsSb for APD applications. This compound semiconductor alloy has a low bandgap energy suitable for absorbing mid-IR photons. The InAsSb material will be combined with a p-i-n avalanche multiplication structure in a unique manner to create a low noise 3-5 micron wavelength APDs.
