A twin-hole optical fiber with pure synthetic silicate glass between the two electrode holes was thermally poled. The induced second-order nonlinearity (SON) was located at the core-cladding interface sections that were nearly parallel to the poling electric field. The polarization dependence of the induced SON suggests that nonlinearity was due to the presence of a space-charge field, which was probably formed by electron migration among the defects located at the core-cladding interface. The magnitude of the induced SON was measured to be approximately 0.06 pm /V.
对一种在两个电极孔之间具有纯合成硅酸盐玻璃的双孔光纤进行热极化处理。诱导产生的二阶非线性（SON）位于几乎与极化电场平行的纤芯 - 包层界面部分。诱导SON的偏振依赖性表明，非线性是由于空间电荷场的存在，该空间电荷场可能是由位于纤芯 - 包层界面处的缺陷之间的电子迁移形成的。测得诱导SON的大小约为0.06 pm /V。
