Technology Behind 810 nm High Power LED

The 810 nm high power LED technology is based on the principles of semiconductor physics. These LEDs are typically made from a combination of gallium arsenide (GaAs) and indium gallium arsenide (InGaAs) materials. The semiconductor structure is designed to create a high electric field, which excites electrons and holes, resulting in the emission of photons at the 810 nm wavelength. The key components of the 810 nm high power LED include the following: 1. Active Region: This is the core of the LED, where the light is emitted. It consists of a thin layer of InGaAs material sandwiched between GaAs layers. 2. P-N Junction: The P-N junction is formed at the interface between the GaAs and InGaAs layers. It allows for the injection of electrons and holes into the active region. 3. Cathode and Anode: The cathode and anode are the electrical terminals of the LED. The cathode is typically made of a metal that is a good conductor of electricity, while the anode is often made of a metal with a low work function to facilitate electron injection. The manufacturing process of 810 nm high power LEDs involves several steps, including epitaxial growth, device fabrication, and packaging. Epitaxial growth is a technique used to create thin layers of semiconductor materials with precise compositions and crystal structures. Device fabrication involves creating the P-N junction and the active region, while packaging involves mounting the LED onto a substrate and connecting it to the electrical terminals.
