Innovative Infrared Beam Diode Technology: Advancing Applications and Efficiency

Introduction to Infrared Beam Diode

What is an Infrared Beam Diode?

An infrared beam diode, also known as an infrared LED (Light Emitting 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, communication systems, medical equipment, and security systems. The infrared beam diode is a key component in the infrared (IR) technology, which is essential for transmitting and receiving signals over short distances.

The working principle of an infrared beam diode is based on the semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have direct bandgap properties, which allow them to emit infrared light when electrons recombine with holes in the material. The emitted light has a wavelength range of approximately 700 to 3000 nanometers (nm), which is beyond the visible spectrum.
