Technology and Materials

High power Infrared LED diodes are typically made using Gallium Arsenide (GaAs) or Aluminum Gallium Arsenide (AlGaAs) as the semiconductor material. These materials have excellent infrared emission properties and can be efficiently lased when excited by an electrical current. The key to achieving high power output in Infrared LED diodes lies in the design and fabrication of the diode structure. The diode is typically composed of a p-n junction, with the p-type material doped with indium or gallium to enhance the electrical conductivity and the n-type material doped with arsenic or antimony to provide a high resistance. The structure is then encapsulated in a package that protects the diode and allows for efficient heat dissipation. One of the most important aspects of high power Infrared LED diode technology is the development of high-quality epitaxial layers. These layers are grown on a substrate using a process called molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). The quality of the epitaxial layers directly affects the performance of the diode, including its brightness, efficiency, and lifespan.
