Top 10 apd Suppliers in China 2025

Introduction to APD

An Avalanche Photodiode (APD) is a highly sensitive semiconductor photodetector that uses the avalanche effect to generate an internal gain of the photocurrent. This makes APDs much more sensitive than ordinary photodiodes, enabling them to detect very weak optical signals. APDs are widely used in various fields such as optical communication, lidar systems, medical imaging, and scientific research. In China, the demand for high - performance APDs has been increasing rapidly in recent years, leading to the growth of many APD suppliers.
