Phlux to explain the technology behind high sensitivity, fast recovery avalanche photodiodes at SPIE Defense + Commercial Sensing event
Sheffield, UK, 12th April 2024: Xiao Collins, co-founder and director of Phlux Technology, a manufacturer of avalanche photodiode (APD) infrared sensors, will present a paper at the SPIE Defense + Commercial Sensing show that explains how Phux’s patented AlGaAsSb avalanche photodiodes (APDs) achieve an order of magnitude greater sensitivity than traditional InGaAs devices and exhibit exceptionally fast recovery times. Phlux APDs recover quickly after illumination by a strong IR pulse
APDs can provide high sensitivity in applications such as laser range finders, LiDAR, and optical time domain reflectometry working at 1550 nm. This is enhanced when the APDs are fabricated in an AlGaAsSb process. Such devices allow operation at high gain without sacrificing noise performance through a high level of dark current or excess noise. …
