摘要 介绍了在用两步离子交换方法制作光功分器中 ,在高斯分布为初始条件下采用平均法求出非线性两步离子扩散方程的折射率分布 ,与实验测出的折射率分布符合得很好。该法尤其对单模光功分器求其折射率更为简单和实用。 An average method is applied to the nonlinear diffusion equation to obtain nonlinear analytical models for the index profiles of two-step ion-exchange splitters. In this way, the models obtained can predict the index profile after two-step exchanging from the first surface index profile (initial condition), which makes a fine curve with Gaussian function.
