This article aims to provide an in-depth introduction to the Far IR LED industry, exploring its history, technology, applications, and future prospects.

History of Far IR LED Technology

The concept of infrared technology dates back to the early 20th century. However, it was not until the 1960s that the first Far IR LED was developed. The invention of the Far IR LED was a significant breakthrough, as it paved the way for various applications in different industries. Over the years, the technology has evolved, with improvements in material science, device design, and manufacturing processes.

Technology Behind Far IR LED

The Far IR LED technology is based on the principles of semiconductor physics. It involves the use of specific materials that can emit infrared light when an electric current is applied. The most commonly used materials for Far IR LEDs are Gallium Arsenide (GaAs), Aluminum Gallium Arsenide (AlGaAs), and Indium Antimonide (InSb). These materials have a direct bandgap, which allows them to emit infrared light efficiently. The manufacturing process of Far IR LEDs involves several steps, including epitaxy, lithography, etching, and metallization. Epitaxy is the process of growing a thin layer of semiconductor material on a substrate. Lithography is used to create the desired pattern on the semiconductor layer. Etching removes the unwanted material, and metallization involves depositing a conductive layer to connect the semiconductor layer to the electrical contacts.
