Design of virtual simulation experiment for multi-scene photonic crystal holographic fabrication

光子晶体是类比晶体结构制作的人工电磁材料,被称为光子半导体。本文利用全息干涉原理设计了二维简单、二维复式和三维简单等多种晶格类型光子晶体的实验光路,并采用Unity、C#、3dsMax等计算机工具开发了上述三种场景的虚拟仿真实验平台。该平台能够实现虚拟激光的产生、传播和再生,以及光束的自动反射、分束等功能,而且支持不同类型光子晶体制作光路的自由设计,具有形象直观、调节方便、图案丰富、低成本、开放性强等优点。

Photonic crystal(PC)are artificial electromagnetic material realized by analogy with crystal structures,known as photonic semiconductors.The experimental optical paths of two-dimensional simple triangular PC,two-dimensional complex square PC,and three-dimensional simple PC have been designed by using multi-beam holographic interferometric method in this paper.The multi-scene virtual simulation experimental platform is developed by using computer tools such as Unity,C#,and 3dsMax comprehensively.This virtual platform can realize the generation,propagation,and regeneration of virtual laser,as well as the automatic reflection,splitting and other functions of the virtual laser beam.Besides,it also supports the arbitrary design of optical path for forming various PC.Such virtual experimental platform possesses the advantages of figurative,intuitive,convenient control,rich patterns,low cost,and strong openness.
