摘要
本文首先指出了算法分裂步骤(split-step)Fourier法和光束传播(propagating-beam)法的等价性.利用这种算法,数字地模拟了可变等振幅孤子脉冲对在无耗光纤中的传输过程,结果证明:提高振幅可使孤子的相互作用大大减小.
It is pointed ont that the Split-step Fourier Method and the Propagating-beam Method are equivalent, and namerically calculated by the method that a pair of soliton pulses propagate in a fiber with bhe initial equal changeable amplitudes-Our results show that the interaction between solitons can be much greately reduced by raising their amplitudes.
