| 摘 要： | 在固体浸没透镜近场光存储中, 光的偏振对近场光场分布具有很大的影响. 采用三维时域有限差分法, 对聚焦线偏振高斯光束通过固体浸没透镜后焦平面上各分量场分布及距离焦平面不同位置光斑图样进行了模拟. 结果表明在焦平面上及距离焦平面较近的近场区域, 出射光场在与入射光偏振垂直方向出现显著的场增强现象, 从而使光斑图样呈近似椭圆分布; 而在距焦平面较远的远场区域光斑图样趋向圆形对称分布. |

| Abstract: | In near field optical storage system of solid immersion lens, the polarization of the incident light affects the near field optical image greatly. In this paper 3 component optical fields intensity of focused linear polarized Gauss beam in the focal plane and the intensity patterns in the sections of various distance from the focal plane are simulated using 3 dimensional finite difference time domain (FDTD) method. The results show that the image pattern in the focal plane or the sections near the focal takes on approximate ellipse, while the patterns in the planes of far region displays asymmetrical round. |
