在孤子光纤通信中,利用孤子形态脉冲取代矩形脉冲编码,利用孤子能量波包的粒子性质,由此可实现长距离高码率通信。孤子光通信又叫量子光通信。目前研制中的器件有孤子激光器、孤子放大器、孤子耦合器、孤子开关、孤子光纤,以及调制不稳定性产生的极高重复率孤子序列等。研究保持光孤子在通过传输介质和介面时的孤子形态,是构 In soliton optical fiber communication, the use of soliton morphology pulse instead of rectangular pulse coding, the use of soliton energy wave packet nature of the particle, which can achieve long-distance high bit rate communication. Soliton optical communication is also called quantum optical communication. At present, the devices under development are soliton lasers, soliton amplifiers, soliton couplers, soliton switches, soliton optical fibers, and very repetitive rate soliton sequences resulting from modulation instability. Studying the soliton morphology of optical solitons as they pass through the transmission medium and interface is a matter of structure
