In this article, we will explore the world of high power 980 nm LED, its working principle, applications, advantages, and future prospects.

Introduction to High Power 980 nm LED

High power 980 nm LED is a type of semiconductor device that emits light at a wavelength of 980 nm. It is widely used in medical, industrial, and consumer applications. The 980 nm wavelength falls within the infrared region of the electromagnetic spectrum, making it invisible to the human eye. This makes it ideal for applications where visible light is not required, such as in medical imaging and optical communication.

Working Principle of High Power 980 nm LED

The working principle of a high power 980 nm LED is based on the quantum dot effect. When a forward bias voltage is applied to the LED, electrons and holes are injected into the active region of the semiconductor material. These electrons and holes recombine, releasing energy in the form of photons. The emitted photons have a wavelength of 980 nm, which corresponds to the infrared region of the electromagnetic spectrum. The key to achieving high power output in 980 nm LEDs is the use of a quantum well structure. This structure consists of a thin layer of semiconductor material with a lower bandgap, sandwiched between two layers of semiconductor material with a higher bandgap. The quantum well structure allows for the confinement of electrons and holes, leading to a higher density of recombination events and, consequently, a higher light output.
