摘要
从理论上探讨了 Ti/Mg 双扩散 LiNbO_3波导的折射率分布变化,并对制成的该种波导样品进行测定.实验已证实:双扩散波导与光纤的耦合性能较佳.
This paper describes a Titanium/Magnesium double diffused LiNbO_3 waveguidewhich symmetrizes the waveguide depth index profile by Mg diffusion after Ti diffusedwaveguide.The index profile is measured and coupling loss reduction between fiber andwaveguide is obtained.
