High power infrared light emitting diode (HP-IRLED) has become an essential component in a wide range of applications, from consumer electronics to industrial automation. This article aims to provide an in-depth introduction to the industry of HP-IRLED, covering its technology, applications, market trends, and future prospects.

Introduction to High Power Infrared Light Emitting Diode

High power infrared light emitting diode (HP-IRLED) is a semiconductor device that emits infrared light at high power levels. It is composed of a p-n junction, which is formed by doping a semiconductor material, typically gallium arsenide (GaAs), with trivalent and pentavalent impurities. When an electric current is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of infrared light. HP-IRLEDs are characterized by their high radiant intensity, which makes them suitable for applications requiring long-distance detection and transmission. They are widely used in various fields, including remote sensing, optical communication, medical imaging, and security systems.

Technology of High Power Infrared Light Emitting Diode

The technology of HP-IRLED involves several key aspects, including material selection, device structure, and manufacturing processes.

Material Selection

The choice of semiconductor material is crucial for the performance of HP-IRLEDs. Gallium arsenide (GaAs) is the most commonly used material due to its direct bandgap, which allows efficient light emission at infrared wavelengths. Other materials, such as indium gallium arsenide (InGaAs) and aluminum gallium arsenide (AlGaAs), are also used in specific applications.

Device Structure

The device structure of HP-IRLEDs plays a significant role in their performance. The most common structure is the single-junction, single-photon diode, which consists of a p-n junction with a wide bandgap semiconductor material. To enhance the radiant intensity, multi-junction and multi-quantum well structures are also employed.

Manufacturing Processes

The manufacturing process of HP-IRLEDs involves several steps, including epitaxial growth, device fabrication, and packaging. Epitaxial growth is used to create the p-n junction, while device fabrication involves the formation of the diode structure. Finally, packaging is performed to protect the diode and ensure its electrical and thermal performance.
