Abstract:Silicon avalanche photodiode (APD) is a highly sensitive semiconductor photo sensor that uses the photoelectric effect converting light to electric charge. APD has high a gain through avalanche multiplication in its p-n junction. APD also has various preferable characteristics such as high quantum efficiency, large dynamic range, light-weight form-factor, robustness and insensitivity to magnetic fields as well as low light measurement capability thanks to its gain of ~100. As a monolithic device, however, it u… Show more
