Avalanche Photodiode Breaks Lidar Performance Levels
Electrical and computer engineers at the University of Virginia and University of Texas-Austin have developed an avalanche photodiode that achieved record performance and has the potential to transform next generation night-vision imaging and Light Detection and Ranging (lidar) receivers. For lidar, the team’s low-noise, two-micrometer avalanche photodiode enables higher-power operation that is eye-safe.

The peer reviewed paper, “Low-noise high-temperature AlInAsSb/GaSb avalanche photodiodes for 2-μm applications,” was published May 18, 2020, in Nature Photonics, a monthly journal of the best research from all areas of light generation, manipulation and detection.
This breakthrough comes from a long-standing collaboration between Joe C. Campbell, Lucien Carr III Professor of electrical and computer engineering at UVA, and Seth R. Bank, Cullen Trust Professor at UT-Austin. Andrew H. Jones, a 2020 Ph.D. graduate advised by Campbell, and Stephen D. March, a Ph.D. student in Bank’s research group, contributed to the research. The team’s work was funded by the Defense Advanced Research Projects Agency and the Army Research Office. Continue reading
