The self-imaging effect based on symmetrical interference in multimode layer-by-layer photonic crystal waveguides (PhCWs), is numerically studied with finite-difference time-domain simulations. With the properties of twofold images, a kind of three-dimensional (3D) PhCW-based power splitters with an ultracompact size using complete photonic bandgaps is proposed, calculated, and analyzed. The presented structure can be extended for the design of M×N power splitters for 3D photonic integrated circuits applications.
基于多模逐层光子晶体波导（PhCWs）中对称干涉的自成像效应，通过时域有限差分模拟进行了数值研究。利用双重图像的特性，提出、计算并分析了一种基于三维（3D）光子晶体的超紧凑尺寸功率分配器，该功率分配器使用了完整的光子带隙。所提出的结构可扩展用于三维光子集成电路应用的M×N功率分配器的设计。
