| 摘 要： | 通过激发光子晶体-光子晶体表面波的方法,设计出了一种由表面修饰光子晶体组成的新型复合结构。利用平面波展开法结合超原胞技术对该结构的耦合表面波色散关系进行了研究,在此基础上利用时域有限差分法对光束在该结构中的传输特性进行了数值模拟,并分析了其物理机制。研究结果表明,所提出的新型结构,对一定频率范围内的传输光,能够实现输出光的分束,此特征可以用来制作光束分束器。

| Abstract: | With the method of exciting surface wave of photonic-photonic, a new compound structure made up of surface modified photonic is designed. Using plane wave expansion method and super cell technology, mode dispersion relations of coupled surface for this structure was studied. Furthermore, numerical simulation of light beam in this structure by finite-difference time-domain (FDTD) method, and analysis of its physical mechanism were carried out. It is found that beam splitting is obtained for incident light of a certain frequency range. This finding can be used to design a beam splitter. |
