Abstract在实际的制备过程中,不可避免地存在非等光强正交圆偏振光制备液晶偏振光栅的情况。为了探究这种情况对制备出的液晶偏振光栅的衍射特性有何影响,本文首次从理论上,利用琼斯矩阵法推导计算出该情况下液晶偏振光栅的衍射特性。首先,计算出两束非等光强正交圆偏振光叠加后的偏振态分布。其次,利用斯托克斯参数表征叠加光场对光控取向膜的折射率响应矩阵。最后,以该响应矩阵为基础,求得液晶偏振光栅的2×2琼斯矩阵。结果表明,非等光强正交圆偏光制备的液晶偏振光栅理论上可以实现0级和1级的光强分布同时受液晶盒盒厚和入射光偏振态的调制,实现0级或±1当中任意级次衍射效率可达100%。在非等光强正交圆偏振光情况下,制备出的液晶偏振光栅依然具有良好的光学特性。
