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 applications, such as remote controls, optical communication, medical diagnosis, and industrial processing. As a key component in the infrared beam diode industry, the technology has been constantly improving and innovating to meet the needs of different fields.

Working Principle of Infrared Beam Diode

The working principle of an infrared beam diode is based on the electron-hole recombination in a semiconductor material. When an electric current is applied to the diode, electrons and holes are injected into the active region of the semiconductor material. As the electrons and holes recombine, they release energy in the form of photons. These photons have a wavelength in the infrared region, which is why the device is called an infrared beam diode. The semiconductor material used in infrared beam diodes is typically a compound semiconductor, such as gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to emit photons efficiently at specific wavelengths in the infrared region.
