摘要

通过片状玻璃模拟光纤拉丝情况并采用正交试验法设计实验,研究了掺稀土磷酸盐玻璃光纤纤芯与包层界面在不同光学加工质量下的微观缺陷。研究表明良好的预制棒加工质量可有效改善光纤纤芯与包层的界面状态,并且相对于纤芯玻璃来说,粘度较高的包层玻璃其加工质量对界面缺陷的影响更为显著。在此研究基础上提出了获得良好界面状态的光学加工条件。

Abstract

Effect of Processing Quality of Glass on Interface Defects Between Core and Cladding of Active Glass FiberLIN Da-yuan,YANG Gang-feng,DENG Zai-de,YIN Bing,ZHANG Qin-yuan(Key Laboratory of Specially Functional Materials and Advanced Manufacturing Technology of Ministry of Education,South China University of Technology,Guangzhou 510640,China)By imitating fiber drawing with glass sheets and adopting orthogonal test,the effect of optical processing quality on microdefects of interface between core and cladding of rare earth doped glass fiber was investigated.The results showed that the better optical processing quality can improve the interfaces between core and cladding.Compared with core glass,the effect of optical processing quality of cladding glass on interface defects was more evident when its viscosity at drawing temperature was higher than that of core glass.According to the analyses,the optical processing condition for obtaining perfect interface was suggested.active glass fiber;perform;processing quality;interface defect
