本文对Fontaine所采用的非线性薄膜波导导模的无量纲表示法作了改进，给出了以无量纲参数表示的芯区为克尔型非线性介质，衬底和包层为线性介质的LNL型非线性平板光波导的有关计算公式，色散曲线族及场分布和功率分布随模折射率变化关系的曲线族。本法易推广应用于其它非线性平板光波导NLL、NNL及NNN等的处理过程。

Improved scaling rules for nonlinear film waveguides given byMarie Fontaine are improved.Using three independent dimensionless parameters,formulas for characteristic analysis,dispersion curves and curves for optical power dispersion versus modal indices are presented for nonlinear Kerr-type film waveguide with linear substrate and cladding (LNL planar guides).The present method can be easily extended to other type nonlinear planar guides NLL,NNL,and NNN,etc.
