摘要
采用时域有限差分(FDTD)方法,研究光在含点缺陷和线缺陷的二维光子晶体中的传输特性。结果表明,缺陷的引入使得在原来不透电磁波的禁带中,出现了缺陷模,即某一波长的电磁波可以透过。基于这个原理,设计了一种由二维光子晶体构成的四通道波分复用系统。
The transmission characteristics of light wave in two-dimensional photonic crystals including point defects and line defects are analyzed by using the finite-difference time-domain method. The result indicates that as the defect is introduced, there will be a defect mode in the gap, and the electromagnetic waves with defect mode frequency can propagate in the structure. On the basis of this principle, we design a four-channel wavelength-division-multiplexing system consisting of two-dimensional photonic crystals.
