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