| 摘 要： | 从理论上提出了一种二维排列的共振吸收介质阵列，计算了介质阵列的透射、反射与吸收光谱，发现存在着类似一维主动光子晶体中的共振光子带隙，并且这种结构的布里渊区边界点与二维阵列中原子之间的频率共振是产生这种共振带隙的必要条件. 本文还进一步分析了光子带隙与结构参数、二维阵列中原子共振中心以及吸收线宽之间的依赖关系.

| Abstract: | A two_dimensional array of resonant absorptive and dispersive medium is proposed. The transmission,reflection and absorption spectra of optical field transmitting in the structure are calculated. The photonic band gap caused by resonance(PBG), similar as the case of one_dimensional active photonic crystal, is observed. It’s found that the resonance between the border of the Brillouin zone and the resonant center of the atom in the array is the key condition for the formation of the PBG. Further discussion is carried on the study of the dependence of transmission spectrum on the structure,the resonant center and the absorption linewidth of the atoms in the array. |
