摘　　要：研究了一维阶梯型函数光子晶体,给出色散关系和透射率的表达式,并与常规光子晶体比较,发现在常规光子晶体中加入缺陷层后,出现明显的缺陷模。而在阶梯型函数光子晶体中加入缺陷层后,缺陷模个数少且强度弱。进一步研究了带缺陷和不带缺陷的阶梯型函数光子晶体的光场分布。发现有缺陷层时,光场强度分布得到增强或者减弱,不同于常规光子晶体中的光强只局域增强。函数光子晶体的这些新的特性对光子晶体的设计与应用具有重要的实际意义。We studied one-dimensional function photonic crystals（PCs） of ladder type,and gave the expression of dispersion relation and transmissivity.We compared the function PCs with convention PCs and find there are defect model obviously,but the number of defect model become small,and the intensity was weak in the function PCs.Further,we researched the characteristic of light transmission in the ladder type function PCs with defect and without defect.With defect,we find the distribution of electric field can be increased or decreased,which is different from the convention photonic crystals electric field distribution increased locally.The new characteristic of function photonic crystals will be applied widely.
