双稳态孤子与其光学转换

Bistable Solitons and Optical Switching

对于有一定非线性的薛定谔方程 ,存在单孤子解的多稳态 ,也就是说对于相同能量 ,单孤子具有不同的传输常数 .以一非线性 ( LSS)模式为例 ,对孤子的双稳态进行理论分析 。

It is demonstrated that a nonlinear Schrodinger equation with certain nonlinearities allows for an existence of multisbalbe singular solitons (i.e.singular solutions with the same carried power but different propagation parameters).Using a paticular nonlinearities (the 'linear+smooth step' model) as an illustrative example,the switching of bistable solitons states of the highly nonlinear (generlised) Schrodinger equation is simulated.
