Photo diode

The current is generated when photons are absorbed in the photodiode. AP Technologies are the UK representatives for Adaptive Lighting, AUREA Technology, Fibotec, Fox Group, IMM Photonics, LDX Optronics, Lumex, Opto Diode Corporation, Oxxius, QD Laser, SensL Technologies, Sensor Electronic Technology and Vertilon. It is also sometimes referred as photo-detector, photo-sensor, or light detector.

Photodiode Characteristics and Applications. Photodiodes are specially designed to operate in reverse bias condition.

It consists of built-in lenses, optical filters, and has small or large surface areas.

Through the electrical contacts (anode and cathode), the generated photocurrent can be obtained. With increase of the surface area, photodiodes have slower response times. Photodiode technology has been successfully and widely used due to its simple and low-cost rugged . They also feature high-speed response, high sensitivity and low noise. The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts. The wide intrinsic region is in contrast to an ordinary p–n diode.
