| 摘 要： | 采用一种简单、稳定的方法-差分迭代法对平行向列相液晶在外电场作用下指向矢的空间分布进行了模拟计算.在此基础上,利用琼斯矩阵方法对平行向列相液晶法布里-珀罗滤光片的本征偏振态及光学特性进行了研究.结果表明,平行向列相液晶法布里-珀罗滤光片的共振模式是两组互相垂直的线性偏振态,且具有调谐范围宽,偏振敏感等特点.

| Abstract: | The configuration of nematic liquid crystal director was calculated with a difference iterative method which is simple and stable. Based on this method, the optical performance and the eigen modes of a nematic liquid crystal fabry-perot filter were analyzed by the Jone matrix method. Results show that there are always two modes propagating in the FP cavity at various voltages which are orthogonal linear polarization state. And the filter has a wide tunable range, but it is sensitive to polarization. |
