综述了近年来复合周期结构光子晶体的最新发展动向，从三种维度阐述了叠层复合和嵌套复合的结构设计思路，通过比较禁带调制性能，认为复合结构较单一结构具有更强的带隙调制作用，其中叠层复合是光子晶体禁带位置及宽度调制的重要手段之一，而嵌套复合主要针对带隙模式的调制。同时还介绍了各种复合结构的制备方法及可能的应用领域。

Current trends of development about complex-period photonic crystal were reviewed. Multi-layer complex structure and nesting complex structure in one-,two-,and threedimension were compared. It can be concluded that the complex structure can produce more photonic bands than single structure. The multi-layer complex structure can adjust the wavelength and width of photonic band,and the nesting complex structure can control the model of band. The preparation and usage of complex structures were also introduced.
