This article aims to provide an in-depth introduction to the high power infrared transmitter diode industry, covering its definition, working principle, applications, and market trends.

Definition and Classification of High Power Infrared Transmitter Diode

High power infrared transmitter diode refers to a semiconductor device that emits infrared radiation at high power levels. It is mainly composed of a diode structure, which includes a p-type semiconductor, an n-type semiconductor, and a p-n junction. The diode is packaged in a housing that allows for the output of infrared radiation. According to the emission wavelength, high power infrared transmitter diodes can be divided into short-wave infrared, mid-wave infrared, and long-wave infrared. Among them, short-wave infrared diodes have the shortest wavelength, while long-wave infrared diodes have the longest wavelength.

Working Principle of High Power Infrared Transmitter Diode

The working principle of a high power infrared transmitter diode is based on the photoelectric effect. When the diode is forward-biased, the electrons in the n-type semiconductor will be injected into the p-type semiconductor. Due to the difference in energy levels between the two semiconductors, the electrons will generate thermal energy and emit infrared radiation when they recombine. The key factors affecting the output power of a high power infrared transmitter diode include the doping concentration, the size of the active region, and the cooling conditions. By optimizing these factors, the output power of the diode can be significantly improved.
