| 摘 要： | 提出一种利用衍射轴棱锥产生三维光格的方法.由广义的惠更斯一菲涅耳衍射积分理论出发.分析准直单色平面光波大角度斜入射轴棱锥形成的光学点阵的特性.数值模拟光束在不同入射角入射轴棱锥情况下,随轴向距离变化的纵向光强分布以及同一轴向距离处的横向光强分布光斑图.结果指出,随着入射轴棱锥角度的增大,在最大无衍射距离内会形成有规则的光学点阵,这种光学点阵与三维光子晶体的结构相近,实验结果与数值模拟相吻合.

| Abstract: | A method of producing three-dimensional facular lattice through a diffractive axicon was proposed. Based on the generalized Huygens-Fresnel diffraction integral theory,the characteristics of the facular lattice generated by a collimated monochromatic plane wave obliquely illuminated on a diffractive axicon with a large incident angle were analyzed. With different incident angles,the optical intensity distribution along the propagation direction and the diffractive optical intensity in a certain axis distanc... |
