掺半导体玻璃波导特性研究

利用离子交换技术制成了单模和多模掺CdSxSe_1-x半导体玻璃波导。通过对波导参数的测量得出这种波导的折射率剖面满足费米函数分布。同时,对这种K⁺—Na⁺离子交换技术得到的单模波导在0.5145μm波长下输入—输出功率的测量,观测到它的功率限制作用。并得到在Ar⁺激光0.5145μm波长下吸收系敲是4cm^-1。在这篇文章中,我们对波导的光功率限制起源于热效应进行了分析和讨论。

STUDY OF PROPERTY OF SEMICONDUCTOR DOPED GLASS WAVEGUIDE

In this paper, the experimental results on the property of ion - exchanged planar waveguides fabricated from doped semiconductor glass are repoeted. By measuring waveguide parameters, we obtained that the profile of refractive index of planar waveguides was shown to be Feimi function. The measurement of the single modewaveguides input- output power shows the optical power limiting in dopedsemiconductor glass waveguide. And the nonlinearity of the waveguide is analysed, analysed.
