The current paper implements three elegant approaches to recover a complete spectrum of optical solitons to the Radhakrishnan-Kundu-Lakshmanan equation with dual-power law of nonlinear refractive index. The conservation laws are also recovered by the usage of multipliers approach. The parameter constraints for the existence of such solitons are also enumerated. The numerical simulations of the recovered soliton solutions are also presented.
本文采用三种精妙方法，针对具有双幂律非线性折射率的Radhakrishnan-Kundu-Lakshmanan方程，恢复了完整的光学孤子谱。通过乘子法也恢复了守恒律。还列举了此类孤子存在的参数约束条件。此外，还给出了所恢复孤子解的数值模拟结果。
