基于平面波展开法研究木堆结构三维光子晶体带隙特性。用硅材料构成木堆结构三维光子晶体,改变结构中木条的宽度和长度,得到当木堆条宽度为5μm,高度为7μm时形成的带隙结构较宽,在0.2899—0.3804Hz,带隙宽度为0.0905Hz。改变构成木堆结构三维光子晶体的材料,得到锗材料构成木堆结构三维光子晶体带隙结构在0.2585—0.3500Hz,带隙宽度为0.0915Hz,带隙相比硅材料和碳化硅材料较宽。研究结论为三维光子晶体的制备提供参考。

Based on the plane wave expansion method, wood pile structure three-dimensional photonic crystal band gap characteristics was studied. Silicon material for wood structure photonic crystals, the change in the structure of strip width and length, is obtained when the wood pile structure width of 5μm, 7μm height is formed when the band gap structure of wide band gap width,in 0. 2899-0. 3804Hz, 0. 0905Hz. Change form wood pile structure in three-dimensional photonic crystal materials, get the germanium material wood structure shape three-dimensional photonic band gap structure in 0. 2585--0. 3500Hz,the band gap width of 0. 0915Hz,band gap compared to silicon and silicon carbide material is wide. Conclusion for the preparation of three-dimensional photonic crystals provide reference.
