High power 980 nm LED, as a cutting-edge technology in the field of optoelectronics, has been attracting increasing attention from both industry and academia. This article aims to provide an in-depth introduction to the high power 980 nm LED, covering its basic principles, applications, market trends, and future prospects.

Basic Principles of High Power 980 nm LED

High power 980 nm LED is a type of semiconductor light-emitting diode (LED) that emits light at a wavelength of 980 nm. It is widely used in various fields, such as medical, industrial, and consumer applications. The basic principle of high power 980 nm LED is based on the quantum confinement effect and the direct bandgap of GaAs-based materials. The quantum confinement effect refers to the phenomenon that the energy levels of electrons and holes in a semiconductor material are quantized due to the confinement of the carriers in a small spatial region. This effect leads to the blue shift of the energy levels and the emission of light at shorter wavelengths. In the case of high power 980 nm LED, the quantum confinement effect is utilized to confine the carriers in a small spatial region, resulting in the emission of light at 980 nm. The direct bandgap of GaAs-based materials is another key factor for the emission of light at 980 nm. Direct bandgap materials have a higher radiative recombination rate, which means that the electrons and holes can recombine directly to emit photons with less energy loss. This characteristic makes GaAs-based materials ideal for high power 980 nm LED applications.
