Introduction to High Power Infrared Transmitter Diode

High power infrared transmitter diode is a kind of semiconductor device that can convert electrical energy into infrared light energy. It is mainly composed of a p-n junction, and its structure is similar to that of a regular diode. When the diode is forward biased, electrons and holes are injected into the depletion region, which results in the recombination of electrons and holes and the release of energy in the form of infrared light. The power output of the diode can reach several watts, and even tens of watts in some cases.

Working Principle of High Power Infrared Transmitter Diode

The working principle of high power infrared transmitter diode is based on the recombination of electrons and holes in the p-n junction. When the diode is forward biased, the injected electrons and holes move towards the depletion region. In the process of moving, the electrons and holes collide and recombine, releasing energy in the form of infrared light. The power output of the diode is determined by the number of electrons and holes that recombine and the energy released during the recombination process.

The power output of high power infrared transmitter diode can be increased by increasing the injection current, improving the optical confinement, and optimizing the device structure. In addition, the use of high-quality semiconductor materials and advanced manufacturing technology can also improve the performance of the diode.
