摘要
给出用以分析非线性包层多量子阱波导ＴＥ模光学非线性与双稳性的理论公式与计算方法。指出用均方根等效折射率法解本征方程是有效的简化方法。用本文方法分析了模折射率对波导总功率的依赖关系，芯区功率与总功率之间的双稳性以及模场分布与模折射率的关系，讨论了波导参数对光学非线性、双稳性及模场分布的影响。
Formulas and method of calculation are presented for analysis of optical nonlinearity and bistability of TE modes in a multiple quantum well waveguide with nonlinear cladding. It is demonstrated that in the thin film approximation, the method of root mean square equivalent index for the waveguide core is an accurate, efficient and time saving method for characteristics analysis. Dependence of modal refractive index on total waveguide power, bistability between core power and total power, dependence of field profile on modal index are analysed and the influence of waveguide parameters on them are discussed.
