From Bulk to 2D: Evolution in Infrared Avalanche Photodiode Technology
The avalanche multiplication effect can be utilized to sense low-power optical signals and even single-photons—thanks to the amplification mechanism within all main: short- (SWIR), near- (NIR), mid- (MWIR), and long wavelength infrared radiation (LWIR) ranges.
