What is the APD of an optical module

Avalanche Photodiodes | MEETOPTICS Academy

Avalanche photodiodes (APDs) are high speed, high sensitivity photodiodes that are designed to operate under specific conditions.

APD Modules

APD modules contain a near infrared or short wavelength type APD. The APD (avalanche photodiode) is a highspeed, high-sensitivity photodiode that internally multiplies photocurrent when

Avalanche Photodiodes: A User''s Guide

For low-light detection in the 200 to 1150 nm range, the designer has three basic detector choices - the silicon PIN detector, the silicon avalanche photodiode (APD) and the photomultiplier tube (PMT).

OverviewHistoryPrinciple of operationMaterialsPerformance limitsFurther reading

An avalanche photodiode (APD) is a highly sensitive type of photodiode, which in general are semiconductor diodes that convert light into electricity via the photovoltaic effect. APDs use materials and a structure optimised for operating with high reverse bias voltage, approaching the reverse breakdown voltage, such that charge carriers generated by the photovoltaic effect are multiplied by an avalanche breakdown; thus

Avalanche photodiodes (APDs) | Hamamatsu Photonics

APDs are photodiodes with internal gain produced by the application of a reverse voltage. They have a higher signal-to-noise ratio (SNR) than PIN photodiodes, as well as fast time response, low dark
