What Does APD Stand For?
APD stands for Avalanche Photodiode
APD, or Avalanche Photodiode, is a highly sensitive semiconductor device designed to detect light and convert it into an electrical signal. Utilizing a mechanism of avalanche multiplication, APDs achieve high gain and are commonly employed in various applications, including fiber optic communications, lidar systems, and medical imaging. Their ability to operate at high speeds and with excellent quantum efficiency makes them integral to advanced photonic systems.
