History of Infrared LEDs

The history of infrared LEDs dates back to the 1960s when the first infrared LEDs were developed. These early devices were primarily used in remote controls and low-power applications. Over the years, advancements in semiconductor technology have led to significant improvements in the performance and efficiency of infrared LEDs. Today, infrared LEDs are widely used in various industries, including consumer electronics, automotive, medical, and industrial automation.

Technology of Infrared LEDs

Infrared LEDs are based on the principle of electroluminescence, where an electric current is passed through a semiconductor material, causing it to emit light. The semiconductor material used in infrared LEDs is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to emit infrared light efficiently. The manufacturing process of infrared LEDs involves several steps, including epitaxial growth, wafer fabrication, and packaging. Epitaxial growth is a technique used to create a thin layer of semiconductor material on a substrate. This layer is then diced into individual chips, which are then packaged into devices.
