Revolutionizing Distance Measurement: The Cutting-Edge Role of Infrared Beam Diode Technology

Infrared beam diode, also known as infrared laser diode, is a type of semiconductor laser diode that emits infrared light. It is widely used in various fields such as communication, medical treatment, industrial automation, and military applications. In this article, we will introduce the industry of infrared beam diode, including its working principle, types, applications, and market trends.

Working Principle of Infrared Beam Diode

The infrared beam diode is a semiconductor device that utilizes the principle of stimulated emission to emit infrared light. When the semiconductor material is excited by an external electric field, electrons and holes are generated. These electrons and holes recombine in the active region of the semiconductor material, releasing energy in the form of photons. The photons with a wavelength in the infrared region are emitted as infrared light.

The working principle of the infrared beam diode can be described by the following steps:
1. Excitation: The external electric field excites the electrons and holes in the semiconductor material.
2. Recombination: The excited electrons and holes recombine in the active region of the semiconductor material.
3. Emission: The recombination process releases energy in the form of photons, which are emitted as infrared light.
4. Modulation: The infrared light can be modulated by an external signal to achieve various communication and control functions.

Types of Infrared Beam Diode

Infrared beam diodes can be classified into several types according to their emission wavelength, structure, and application fields. The main types include:

1. Near-infrared beam diode: The emission wavelength is between 0.75μm and 3μm, which is mainly used in optical communication, remote sensing, and medical treatment.
2. Mid-infrared beam diode: The emission wavelength is between 3μm and 30μm, which is mainly used in thermal imaging, spectroscopy, and gas detection.
3. Far-infrared beam diode: The emission wavelength is between 30μm and 1000μm, which is mainly used in astronomy, military applications, and industrial automation.

According to the structure, infrared beam diodes can be divided into edge-emitting diodes and surface-emitting diodes. Edge-emitting diodes have a higher power output and are suitable for long-distance communication. Surface-emitting diodes have a smaller size and are suitable for short-distance communication and optical storage.
