Optimizing avalanche photodiode design for photodetection in the ultraviolet wavelength

Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons. Photons of certain wavelengths, when absorbed by photodiodes, generate electron-hole pairs in a process called impact ionization which can result in a multiplication of charges when occurring in an electric field.

IEEE Research Advances Avalanche Photodiode Design for Enhanced Ultraviolet

In a groundbreaking advance for ultraviolet photon detection technology, researchers have developed a sophisticated numerical model to design Geiger-mode avalanche photodiodes (GM-APDs) with enhanced sensitivity in the near-ultraviolet (NUV) spectrum. GM-APDs are at the forefront of single-photon detection technology, capable of sensing individual photons with remarkable precision. These devices rely on the principle of impact […]
