Second-harmonic microscopy has been successfully applied to characterize the second-order nonlinear layer in optical fibers thermally poled at 280 degrees C and 3.5 kV for 30 min. The nonlinear layer was found to be approximately 5.1 microm deep under the anode and was not always centered about the closest point between the electrodes.
二次谐波显微镜已成功应用于表征在280摄氏度和3.5千伏下热极化30分钟的光纤中的二阶非线性层。发现非线性层在阳极下方约5.1微米深处，并且并不总是位于电极之间最近点的中心。
