High power infrared transmitter diode, as a key component in the field of optoelectronics, plays a crucial role in various applications such as infrared communication, remote control, and sensing. This article aims to provide an in-depth introduction to the industry of high power infrared transmitter diodes, covering their basic principles, development history, application fields, and future trends.

Basic Principles of High Power Infrared Transmitter Diode

High power infrared transmitter diode is a semiconductor device that converts electrical energy into infrared light. It consists of a p-n junction, which is formed by doping a semiconductor material with impurities. When an electrical current is applied to the diode, electrons and holes are injected into the depletion region, and then recombine to emit photons with infrared wavelengths. The key parameters of a high power infrared transmitter diode include forward voltage, forward current, output power, and modulation bandwidth. The forward voltage is the voltage required to forward bias the diode, and the forward current is the current flowing through the diode when it is forward biased. The output power is the power radiated by the diode, and the modulation bandwidth is the frequency range over which the diode can be modulated.
