The basic principle of the photodetector is that when an incident light or radiation falls on the surface of detector and
Principle of photodetectors in optical modules
A photodetector is a sensor that converts light into an electrical signal. They are essential for many scientific executions, such as fiber optic systems for communication, controlling processes, environmental mon-itoring, safety and security, and defense-related purposes. It details the various types, including semiconductor-based devices like photodiodes and avalanche photodiodes, vacuum-based detectors such as photomultiplier tubes. Therefore, we can directly conclude that a photodetector can be defined as a device that is used to detect light radiations by absorption.
