Advancements in Infrared Diode Technology: Exploring the Future of Optoelectronics

Infrared diodes, also known as infrared LEDs, are semiconductor devices that emit infrared radiation when an electric current is applied to them. As a crucial component in various applications, infrared diodes have become increasingly popular in the industry due to their compact size, low power consumption, and high efficiency. This article will provide an in-depth introduction to the infrared diode industry, covering its history, types, applications, and future prospects.

History of Infrared Diodes

The history of infrared diodes dates back to the early 20th century when scientists discovered that certain materials could emit infrared radiation when excited by electricity. In 1906, the German physicist Henry Becquerel discovered that selenium emits infrared radiation when exposed to light, which laid the foundation for the development of infrared diodes. In the 1930s, the American physicist O. Herrick and his team successfully developed the first infrared diode based on selenium. Since then, infrared diodes have undergone continuous technological innovation and have been widely used in various fields.

Types of Infrared Diodes

There are mainly two types of infrared diodes: photodiodes and photovoltaic diodes. Photodiodes are used to convert infrared light into electrical signals, while photovoltaic diodes are used to convert infrared light into electrical energy.

• Photodiodes: Photodiodes are semiconductor devices that convert light into electrical current. They are widely used in applications such as optical communication, remote control, and infrared sensors. According to the wavelength of the emitted light, photodiodes can be divided into near-infrared, mid-infrared, and far-infrared photodiodes.
• Photovoltaic diodes: Photovoltaic diodes are also known as infrared solar cells. They convert infrared light into electrical energy and are used in applications such as infrared detectors, infrared cameras, and infrared remote controls.
