Avalanche photodiodes (APDs) represent a cornerstone of modern photodetection technologies, employing the impact ionisation process to multiply weak optical signals and thereby enhance sensitivity.

X-Fab Silicon Foundries has added a photodiode-specific process core module to its XS018 180nm CMOS sensor process – previously XS018 had been focused on the fabrication of multi-pixel CMOS image ...

Researchers developed a type of infrared photodiode that is 35% more responsive at 1.55 m, the key wavelength for telecommunications, compared to other germanium-based components. Detecting infrared ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major ...

(Nanowerk News) The near-infrared light is a light source with the shortest wavelength, indicated outside of the red color in the light spectrum. The near-infrared light has been widely used in ...

Silicon-based photodiodes are widely used due to their low cost, low noise, and compatibility with standard IC technologies. However, silicon has a bandgap of 1.12 eV—equivalent to a wavelength of ...
