抛物型折射率包层的铌酸锂单晶光纤

Lithium Niobate Single Crystal Fiber withParabolic Refractive Index Cladding

利用镁离子内扩散的方法，实现了铌酸锂单晶光纤具有抛物型折射率包层的波导结构。对扩散层中的镁离子浓度分布进行了理论模拟，理论和实验结果相符合。

Lithium niobate single crystal fiber with parabolic refractive index profilecladding is achieved by using Mg-ion indiffusion process. Mg-ion concentration profilesof the magnesium diffused layer by theoretical simulation are close to the experimentalresults.
