用锥形光纤改进孤子传输光纤放大器的发展，打开了通往长距离全光通信的大门。未来的高速光通信系统很可能要利用光孤子——一种沿光纤传播而几乎不变形的脉冲。但对孤子通信来说也有一个限制性因素，即孤子长距离传输后发生的能量损耗。随着脉冲能量的下降，非线性光学效... Using tapered optical fibers to improve the development of soliton-transmitting fiber amplifiers opens the door to long-distance all-optical communications. High-speed optical communication systems in the future are likely to use optical solitons - a kind of pulse that travels almost evenly along the fiber. But there is also a limiting factor for soliton communication, which is the loss of energy that occurs after long solitons are transmitted. With the drop of pulse energy, nonlinear optical effect ...
