摘要: |
引入简单镜像对称的一维二元光子晶体结构模型,应用传输矩阵方法研究在该镜像对称的一维二元光子晶体结构模型两端加入高折射率介质时的光子带隙结构.结果表明,加入较高的折射率介质时,光子晶体原来的带隙结构中存在的窄的共振透射峰变宽,且随着势垒的不断增加,分裂的共振峰变得越来越细,中间的共振峰透过率一直保持在100%,而两侧的峰高则有所降低;当两端加入的介质折射率进一步提高,这时共振透射峰分裂为3个窄的共振透射峰,同时还在其他波长处出现多个窄的透射峰.这种带隙结构可以用来设计优异理想窄带滤波器. |

Abstract: |
Band gap structures of 1D-two element photonic crystals with simple mirror symmetry and with much higher refractiveindexes are calculated by usingtransfer matrix method.The results indicate that the narrow resonance transmission peak in photonic band gap becomes wider when adding two higher refractive indexes dielectric at it.When the two dielectrics refractive indexes become much higher, the resonance transmission peak split into three narrow resonance peaks, at the same time there are many new narrow transmission peak sappearing in transmission spectrum.This is an ideal capability in designing excellent light wave filter. |
