Diode IR, or Infrared Diode, is a type of semiconductor device that emits infrared radiation when forward biased. It is widely used in various applications, such as remote controls, night vision devices, and fiber optic communication systems. This article aims to provide an in-depth introduction to the diode IR industry, covering its working principle, applications, market trends, and future prospects.

Working Principle of Diode IR

Diode IR operates based on the principle of semiconductor physics. When a diode is forward biased, electrons and holes are injected into the depletion region. Due to the recombination of electrons and holes, infrared radiation is emitted. The wavelength of the emitted radiation depends on the material and structure of the diode. The diode IR is typically made of materials such as gallium arsenide (GaAs), gallium nitride (GaN), and indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to emit infrared radiation efficiently. The diode IR emits radiation in the infrared spectrum, ranging from 0.7 to 30 micrometers.
