【摘要】 本文提出了在熔盐中加Li~+和分阶段离子交换制造非均匀光波导的新方法。计算表明,用改进的工艺制造非均匀介质光波导,其折射率分布可以得到明显的改善。更多还原

【Abstract】 In this paper a new method by using the molten salt add in some Li~+ and exchanging ions in more than one step of manufacture techniques for hihomogeneous dielectric optical waveguides is progosed. The calcu lat ion show that, if the inhomogeneous dieletric optical waveguies is manu ia ctured by this new method its index distribution will be improved signi ficantly,更多还原
