| 摘 要： | 研究了被激波调制的光子晶体对入射光产生的频率转换效应.建立了弹性激波调制一维光子晶体的物理模型:提出了准静态带隙结构的概念,并采用FDTD和平面波展开法计算了其光子带隙;通过数值计算和微扰分析,发现该频率转换是一个量化累积过程,并对该频率转换效应及其量化累积现象提出一种基于光子-声子相互作用和表面衰减模的解释,同时,分析了该频率转换效应的特性.

| Abstract: | Frequency shift effect in photonic crystals modulated by shock wave was studied. The physical model of one-dimension photonic crystals modulated by shock wave was built. Quasi-static bandgap structure was put forward,and its bandgap was calculated using Finite-difference Time-domain (FDTD) and Pulse Width Modulation (PMW). By performing numerical computation and perturbation analysis,the incidence frequency increased by integral multiple of a certain amount in the process of frequency conversion was found,a... |
