一、光纤孤子通信 当今在世界范围内,光纤通信正蓬勃发展。然而这一通信技术并不很理想,一是由于光脉冲在光纤中传输时有光损耗,使光的能量不断地衰减,为了实现长距离光通信就得在一定距离建立中继站,把衰减的信号反复增强;二是光纤色散效应限制了光通信系统的传输容量。为了增大光脉冲的传输距离和信息容量,美国学者哈瑟加瓦在1973年就提出了在光纤中实行光孤子(Optical Soliton)传输的概念。1980年,美国贝尔实验室的研究人员第一次从实验中观测到了
First, the optical fiber soliton communication Today in the world, optical fiber communication is booming. However, this communication technology is not very satisfactory. The first is that optical pulses are lost in optical fiber transmission and the energy of the optical attenuates continuously. In order to realize long-distance optical communication, a relay station needs to be established at a certain distance, and the attenuated signal Repeatedly enhanced; Second, the optical fiber dispersion effect limits the optical communication system transmission capacity. In order to increase the optical pulse transmission distance and information capacity, American scholar Hasegawa proposed the concept of implementing optical soliton transmission in optical fiber in 1973. For the first time, researchers at Bell Laboratories in the United States observed it in 1980
