There are conduction and valence bands in semiconductor materials
It can also turn the energy of electricity into light, and the width of the forbidden band of the material determines the working wavelength of the optoelectronic device. The development of materials science enables us to use the energy band engineering of semiconductor materials for a variety of exquisite cutting, so that it can meet our various needs and do more things for us, but also to make the semiconductor optoelectronic devices work wavelength breakthrough material band gap width limit extended to a wider range.

According to the characteristics of the light source, it can be divided into laser communication and non-laser communication; according to the transmission medium, it can be divided into atmospheric laser communication and optical fiber communication; according to the transmission band, it can be divided into visible light communication, infrared optical communication and ultraviolet communication. Light is an electromagnetic wave with a wavelength usually in the range of 1 × 103 to 5 × 10-3 microns. The frequency of light is high, the frequency bandwidth of optical communication, the communication capacity is large, and the anti-electromagnetic interference ability is strong. Laser communication is the use of laser transmission of information

Microscopic particles have a specific set of energy levels (usually these energy levels are discrete). A particle can only be in a state corresponding to a certain energy level at any one time (or simply expressed as being at a certain energy level). When interacting with a photon, the particle transitions from one energy level to another and accordingly absorbs or radiates the photon. The energy value of the photon is the energy difference △E between the two energy levels, and the frequency is ν = △E/h(h is Planck's constant).
