Introduction to Infrared Beam Diode

What is an Infrared Beam Diode?

An infrared beam diode, also known as an infrared laser diode, is a semiconductor device that emits infrared light when an electric current is applied. It is widely used in various fields, such as industrial automation, medical treatment, communication, and security. As a key component of infrared light-emitting devices, the infrared beam diode plays a crucial role in modern society. The working principle of an infrared beam diode is based on the quantum tunneling effect in a semiconductor. When a forward bias voltage is applied to the diode, electrons and holes are injected into the active region, and the recombination of electrons and holes releases energy in the form of photons. These photons have a wavelength in the infrared region, ranging from 0.75 to 3.0 micrometers.
