【摘要】 对芯子为克尔型非线性介质、覆盖层和衬底为线性介质的平板波导，在弱非线性近似下，导出了这类波导横向电场波满足的色散方程和场分布，其物理意义清晰，且大大降低了数值计算的强度更多还原

【Abstract】 A new treatment of the behavior of TE waves in a planar waveguide with Kerr type nonlinearity is given in the weakly nonlinear approximations. Dispersion equations and field profiles with clear physical insight are presented. This method simplifies the numerical calculations significantly.更多还原
