【摘要】 提出一种基于Matlab GUI数值模拟多光束干涉形成三维光子晶格结构的方法,通过模拟计算干涉图像光强的分布可以直观地观测光子晶格形状,并探讨了部分参数对光子晶格的影响。在具体的模拟过程中,采用(6+1)束光进行干涉,中心光束为涡旋光,其余6束光环绕中心对称分布。以往通过实验装置研究光子晶格的方法往往误差大,装置调整复杂,实验周期长;而基于Matlab GUI的光子晶格数值模拟方式不仅效率高、误差低、结果直观,而且具有参数调节灵活快速,用户交互友好等优点。更多还原

【Abstract】 A numerical simulation method of multiple-beam interference to produce three-dimensional photonic lattice structure based on Matlab GUI was proposed. The photonic lattice structures could be observed intuitively by calculating numerically the light intensity distributions of the interference patterns. Moreover, the influence of some parameters on the structures was discussed. In the concrete simulation process,(6+1) beams to interference,where the central beam is a vortex beam, was used, and the remaining six beams distributed symmetrically around the center beam. In the past, the method to study the photonic lattice by experimental device was with serious errors, involving complex device adjustment and long experiment period. Nevertheless, the numerical simulation method based on Matlab GUI in the study has not only high efficiency, low error and intuitive results, but also flexible and fast parameter adjustment, user interface friendliness, and other advantages.更多还原
