History of Infrared LEDs

The history of infrared LEDs dates back to the early 1960s when Nick Holonyak, a physicist at General Electric, successfully developed the first practical infrared LED. This discovery marked the beginning of a new era in optoelectronics. Over the years, the technology has evolved significantly, with improvements in efficiency, brightness, and lifespan. Today, infrared LEDs are widely used in various industries, thanks to their unique properties and applications.

Technology of Infrared LEDs

Infrared LEDs are semiconductor devices that emit infrared light when an electric current passes through them. They consist of a p-n junction, where the p-type and n-type materials are doped with impurities to create a potential barrier. When an electric current is applied, electrons from the n-type material move towards the p-type material, releasing energy in the form of infrared light.

The key factors that determine the performance of an infrared LED include its material, structure, and manufacturing process. The most commonly used materials for infrared LEDs are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have different emission wavelengths, which can be tailored to meet specific application requirements.

The structure of an infrared LED typically includes a p-n junction, a reflector, and an encapsulant. The reflector is designed to enhance the light output by reflecting the emitted infrared light back into the device. The encapsulant protects the LED from environmental factors, such as moisture and temperature variations.

The manufacturing process of infrared LEDs involves several steps, including epitaxial growth, wafer fabrication, chip fabrication, and packaging. Epitaxial growth is used to create a thin layer of semiconductor material on a substrate. Wafer fabrication involves slicing the epitaxial wafer into individual chips. Chip fabrication includes processes such as cleaving, dicing, and bonding. Finally, the packaging process involves encapsulating the chip in a protective housing to ensure its longevity and reliability.
