Diode IR, or Infrared Diode, is a crucial component in the field of infrared technology. It plays a vital role in various applications, including remote controls, thermal imaging, and optical communication. This article aims to provide an in-depth introduction to the diode IR industry, covering its history, technology, applications, market trends, and future prospects.

History of Diode IR Technology

The history of diode IR technology dates back to the early 20th century when infrared radiation was first discovered. However, it was not until the 1950s that the first infrared diode was developed, marking the beginning of the diode IR industry. Since then, the technology has evolved significantly, with continuous advancements in materials, design, and performance.

Technology of Diode IR

Diode IR technology is based on the principle of semiconductor physics. When a forward bias is applied to a semiconductor material, electrons and holes are injected into the depletion region, creating a current flow. In the case of an infrared diode, this current generates infrared radiation when the diode is forward biased. The key parameters of a diode IR include its wavelength, bandwidth, and power output.

Modern diode IRs are typically made from materials such as gallium arsenide (GaAs), gallium nitride (GaN), and indium gallium arsenide (InGaAs). These materials are chosen for their ability to emit infrared radiation efficiently and their compatibility with the fabrication process. The structure of a diode IR usually consists of a p-n junction, with a layer of active material sandwiched between the p-type and n-type regions.
