Revolutionizing Infrared Communication: The Power of High Power Infrared Transmitter Diode

High power infrared transmitter diode, as an essential component in the field of infrared communication and sensing, has been widely used in various applications such as industrial automation, medical equipment, and consumer electronics. This article aims to provide an in-depth introduction to the industry of high power infrared transmitter diodes, covering their basic principles, types, applications, and future development trends.

Basic Principles of High Power Infrared Transmitter Diode

High power infrared transmitter diode is a semiconductor device that converts electrical energy into infrared radiation. It is typically made of gallium arsenide (GaAs) or indium phosphide (InP) materials, which have excellent optical and electrical properties. The working principle of high power infrared transmitter diode is based on the internal photoelectric effect.

When a forward bias voltage is applied to the diode, electrons and holes are injected into the active region. Under the action of the electric field, electrons and holes recombine, releasing energy in the form of photons. These photons are then emitted as infrared radiation. The intensity of the infrared radiation is proportional to the injection current and the quantum efficiency of the diode.
