The semiconductor itself is a special material, and the semiconductor light-emitting diode is a device that can emit light. The main material is a semiconductor, and its structure is a combination of PN, which is a kind of diode material that can emit light. The range of light emission is so large that people can clearly see it with naked eyes. However, some scholars now redefine light-emitting diodes to include some near-infrared and infrared light-emitting tubes. For example, the wavelength of GaAs light-emitting diodes is wider than that of semiconductor light-emitting diodes. In addition, there is a very special light-emitting diode, which is the superluminescent light-emitting diode. In fact, its structure is a combination of the materials of light-emitting diodes and laser diodes, and also combines the advantages of these two diodes, and can be used in optical fibers. play an important role in applications such as
