Diode IR, or Infrared Diode, has become a crucial component in the field of optoelectronics, playing a pivotal role in various applications such as remote sensing, infrared communication, and thermal imaging. This article aims to provide a comprehensive introduction to the diode IR industry, covering its history, technology, applications, market trends, and future prospects.

History of Diode IR

The concept of diode IR technology dates back to the early 20th century when the first semiconductor materials were discovered. However, it was not until the 1950s that diode IR technology started to gain traction with the invention of the first practical infrared diode by Texas Instruments. Since then, the technology has evolved significantly, with numerous advancements in materials, design, and manufacturing processes.

Technology of Diode IR

Diode IR devices are based on the principle of the photoelectric effect, where a semiconductor material emits an electric current when it absorbs infrared radiation. The key components of a diode IR are the semiconductor material, the p-n junction, and the metal contact. The most commonly used semiconductor materials for diode IR are gallium arsenide (GaAs), indium phosphide (InP), and cadmium telluride (CdTe). The p-n junction is formed by doping a semiconductor material with impurities to create a region with excess electrons (n-type) and a region with excess holes (p-type). When infrared radiation strikes the p-n junction, it can generate electron-hole pairs, which are then separated by the electric field across the junction, resulting in an electric current.
