We present a novel method for forming linearly polarized axially symmetric beams with various polarization orders that is based on computer-generated space-variant subwavelength gratings. We introduce and experimentally demonstrate that our space-variant polarization state manipulations are accompanied by a phase modification of a helical structure that results from the Pancharatnam-Berry phase. We have verified the polarization properties of our gratings for laser radiation at 10.6-microm wavelength.
我们提出了一种基于计算机生成的空间变体亚波长光栅来形成具有各种偏振阶数的线性偏振轴对称光束的新方法。我们介绍并通过实验证明，我们的空间变体偏振态操纵伴随着由潘查拉特纳姆 - 贝里相位产生的螺旋结构的相位修改。我们已经验证了我们的光栅对于10.6微米波长激光辐射的偏振特性。
