Abstract

When the laser transmits in the fiber, it will produce dispersion, and the dispersion is usually expressed by the time delay difference. The reason for dispersion is that the propagation speed of light with different frequencies in the fiber is different with the increasing transmission distance during the transmission of optical signals in the fiber. The light emitted by all light sources has a certain bandwidth, and the optical transmission delay at different frequencies is different, which leads to delay difference. Time delay difference is the time difference caused by different modes or different wavelength components transmitting the same distance in an optical pulse. Because of this time difference, the laser pulse will be broadened, which is a physical effect. For an optical communication system, dispersion will affect the transmission capacity of the system, and also adversely affect the relay distance. The existence of dispersion will also affect the confusion of optical signals at the receiver, cause mutual interference between optical signal numbers, and generate wrong signal codes. This increases the bit error rate of optical signal reception, which is extremely harmful to the optical communication system. We must find ways to eliminate this adverse effect. By analyzing the causes of dispersion, a thulium doped fiber laser based on dispersion compensation is designed, a method of laser dispersion compensation is proposed, and a scheme of laser dispersion compensation is presented. The experimental results show that the intracavity dispersion can be changed by introducing a dispersion compensation system, so that the optical pulse signal can basically restore the original pulse shape. The design scheme proposed in this paper can compensate the dispersion to some extent, and the proposed dispersion compensation method is effective.
