This article aims to provide an in-depth introduction to the industry of 850nm LED, covering its technology, applications, market trends, and future prospects.

Introduction to 850nm LED

850nm LED, also known as an 850nm light-emitting diode, is a type of semiconductor device that emits light at a wavelength of 850 nanometers. It is widely used in fiber optic communication systems due to its excellent performance in terms of high speed, long distance, and low power consumption. The 850nm band is part of the infrared spectrum, making it invisible to the human eye.

Technology of 850nm LED

The technology behind the 850nm LED involves the growth of semiconductor materials, typically gallium arsenide (GaAs), which is doped with indium to create a p-n junction. When an electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of light. The specific composition and structure of the semiconductor material determine the emission wavelength, which in this case is 850nm.

Manufacturing processes for 850nm LEDs include epitaxial growth, which involves depositing layers of semiconductor material on a substrate to create the desired structure. The quality of the epitaxial layers is crucial for the performance of the LED, as it affects factors such as the light output, efficiency, and reliability. After the epitaxial growth, the LEDs are processed through several steps, including cleaving, bonding, and packaging, to create a finished product.
