Bi_(12)SiO_(20)晶体的生长及其在集成光学中的应用

Growth of Bi_(12)SiO_(20) Crystal and Its Application in Integrated Optics

通过选择合适的温场和生长工艺参数,生长过程中保持等径生长和平坦的固液界面,生长出具有优良光学性能的 Bi_(12)SiO_(20)(BSO)晶体,消除了晶体生长过程中常见的缺陷。晶体在800℃通氧退火,提高了晶体的光透过率,改善了晶体的光学性能和加工性能。利用优质 BSO 晶体制成了耦合棱镜,用它研究了 LiNbO_3晶体光波导基片的光损伤,观察到清晰的 m 线输出图像。

BSO (Bi_(12)SiO_(20)) crystal,which have high transmissivity and re-fractive index,is a kind of material for waveguide coupling prism.Thegrowth of erystal,the manufacture and application in integrated optics ofBSO coupling prism are reported in this paper.
