摘要
首先讨论和比较了两种不同诱导石英光纤的方案，即掺杂物和／或光诱导方案及电场诱导方案，分析了它们各自的特点，在此基础上提出了一种新的诱导方法。预期新方法诱导出石英光纤的二阶非线性系数可与ＬｉＮｂＯ３的二阶非线性系数ｄ３１相比拟。
The two different kinds of schemes for silica fiber poling,adulterant and/or photoinducing and electrical poling,are discussed in the paper.The differences of their intrinsic characteristics are analyzed.And then a new kind of poling scheme is brought forward.It is anticipated for the silica fiber poled by this means that its second order nonlinear coefficient can compare with that of LiNbO 3.
