激光全息法制作二、三维光子晶体相比于传统半导体微加工及精密机械加工技术具有很多优势,比如通过一次光辐射就可以制作出大体积、均匀的周期性结构,且能更自由、更容易地控制光子晶体结构.提出一种多光束干涉模型,通过设计模型中光束的各项参数,计算分析出二、三维光子晶体的结构.基于平面波展开法,理论计算了fcc结构光子晶体的完全禁带随填充率和介电常数比变化的情况.以上计算结果为后期实验中采用激光全息法制作二、三维光子晶体结构提供了良好的指导方向和理论依据.
Laser holography produces two- and three-dimensional photonic crystals that have many advantages over traditional semiconductor micromachining and precision machining techniques, such as the ability to create large, uniform, periodic structures with a single optical radiation and to be more free and easier And control the structure of photonic crystal.A multi-beam interference model is proposed and the structures of two-dimensional and three-dimensional photonic crystals are calculated and analyzed by designing various parameters of the beam in the model.According to the plane wave expansion method, the complete banned of fcc photonic crystal With the filling rate and dielectric constant ratio changes in the above results for the latter part of the experiment using laser holographic method to produce two or three-dimensional photonic crystal structure provides a good direction and theoretical basis.
