| 摘 要： | 文章采用FDTD(时域有限差分)法,通过数值计算得到了一种新型PCRR(光子晶体环形谐振腔)的宽带频响特性,并分析了介电常数对PCRR传输特性的影响。在此基础上建立了一个三波长的光子晶体分频器,结合对该模型中光场强度动态分布图的分析,实现了在1 5001、550和1 610 nm 3个波长处的分频功能。数值结果表明:与微腔特性相比,PCRR能同时得到多个窄频信号,并且在多波长分频器中可以减少微腔的个数;与波导耦合相比,在结构参数设计上更加灵活。

| Abstract: | In this paper,using Finite Difference Time Domain(FDTD) method,we numerically obtain the broadband frequency response characteristics of a new type of the Photonic Crystal Ring Resonator(PCRR) and analyze the impact of changing the dielectric constant on the transmission characteristics of PCRR.On this basis,we establish a three-wavelength photonic crystal divider,and in connection with the analysis of the dynamic distribution of light intensity in this model,achieve the frequency division at 1 500,1 550 an... |
