摘 要: | 对Ti扩散LiNbO_3波导分别采用双曲正割和抛物线分布来近似其折射率的高斯分布,在两个波长下由相应的两种近似本征值方程分别推得了单模波导参数的计算公式,并在4880(?)和6328(?)激光波长下利用棱镜耦合器测量了单模波导参数,对测量结果给出必要的理论分析。

Parameter measurement of Ti diffused LiNbO3 single-mode waveguides |
| |
Abstract: | For Ti diffused LiNb03 guides the Gaussion profile of the guide refractive index has been approximated respectively by hyperbolical-secant and parabolical profile, calculation formulae of single-mode guide parameters have been derived respectively by corresponding approximation eigenvalue equations at two optical wavelengths, and parameters of single-mode guides have been measured with a prism coupler, and necessary theoretical analysis on the measured results are given. |
