High power infrared transmitter diode is a crucial component in various applications, including industrial automation, remote control, and communication systems. This article aims to provide an in-depth introduction to the industry of high power infrared transmitter diodes, covering their working principles, applications, market trends, and future prospects.

Working Principles of High Power Infrared Transmitter Diode

High power infrared transmitter diodes are based on the principle of semiconductor physics. They are made of semiconductor materials, such as gallium arsenide (GaAs) or indium phosphide (InP), which have a direct bandgap. When a forward bias voltage is applied to the diode, electrons and holes are injected into the active region, where they recombine and emit infrared radiation. The working process of a high power infrared transmitter diode can be divided into several stages: 1. Injection: Under forward bias, electrons and holes are injected into the active region of the diode. 2. Recombination: Electrons and holes recombine in the active region, emitting infrared radiation. 3. Emission: The emitted infrared radiation is coupled out of the diode through an optical cavity, which enhances the radiation intensity. 4. Detection: The emitted infrared radiation is detected by a receiver, which converts the optical signal into an electrical signal for further processing.
