| 摘 要： | 提出了一种基于二维光子晶体微环腔的新型光分叉复用器,并可以通过改变环区的硅介质柱的折射率实现波长调谐.运用经典的微环自由光谱范围FSR和微环半径R的关系,证实新型的光子晶体微环腔也满足该关系.利用二维时域有限差分法系统分析了下路信号波长及相应效率随折射率的变化关系.结果表明,只需改变环区折射率0.005,下路波长就可以漂移1 nm,而有效微环半径还不足1.4 μm. |

| Abstract: | A new tunable OADM based on photonic crystal ring resonators (PCRRs) is proposed by changing the silicon rod index of ring region.The provided PCRR also satisfies the well-known relationship between free spectral range (FSR) and ring radius R of traditional micro-strip ring resonators.The effect of index change on the dropped wavelength and its corresponding efficiency are then numerically analyzed by using two-dimensional finite-difference time-domain (FDTD) technique with perfectly matched layers (PML) as absorbing boundaries.1-nm dropped wavelength shift can be obtained with only 0.005-Δn and less than 1.4 μm effective ring radius. |
