一维光子晶体中光场分布特性分析

摘要

In this paper, we give the expressions of transmissivity, reflectivity and the distribution of election field in a photon crystal at an arbitrary incidence angle. We investigate the field intensity when angle frequency of incidence light is odd or even times the fundamental frequency in photon crystal. Besides, we study the effects of incidence angle, the incident direction of light and defect layer on election field distribution, and obtain some new and valuable results. We expect the research results to be helpful for designing photonic crystals.%给出了在任意入射角下光子晶体的透射率、反射率及光在光子晶体内部场强分布的正确表达式．在此基础上，研究了入射光角频率分别为基频奇数倍、偶数倍时在光子晶体内部的场强分布．此外，还研究了不同入射角、光入射方向及缺陷层对场强分布影响，得到了一些新的有价值的结果，这为光子晶体的制备提供了依据．
