Photodiode Detectors

A photodiode detector is a semiconductor device that converts light into an electrical current. It operates based on the principle of the photoelectric effect, where photons of light incident on the photodiode generate electron-hole pairs within the semiconductor material. These electron-hole pairs create a flow of current within the device, which can be measured as a signal. Photodiode detectors are commonly used in various applications such as optical communications, light sensing, and imaging systems due to their high sensitivity and fast response time.
