通过观察SHG干涉bR薄膜，我们发现通过简单的浸涂技术制备的薄膜具有C无穷对称的极性取向。 SHG干涉测量是在不同入射角的各种输入和输出偏振组合下或在特定入射角旋转四分之一波延迟板的情况下进行的。干涉图案使我们能够深入了解包括手性分量在内的非零非线性光学系数的特性。利用两片手性SH活性薄膜观察SHG干涉可以获得丰富的信息。 (C) 2012 Elsevier B.V. 保留所有权利。
We show that by observing SHG interference bR thin films prepared by a simple dip coating technique have a polar orientation with C-infinity symmetry. The SHG interference measurements were performed under various input and output polarization combinations at different incident angles or under the rotation of the quarter-wave retardation plate at specific incident angles. The interference patterns provide us with insight into the characteristics of non-vanishing nonlinear optical coefficients including chiral components. Abundant information can be obtained by observing SHG interference by using two chiral SH active films. (C) 2012 Elsevier B. V. All rights reserved.
