利用传输矩阵方法 ,从理论上研究了金属插层对由Si SiO2 组成的一维光子晶体中光传输特性的影响 .结果表明 :由 (Si SiO2 ) n 组成的一维光子晶体 ,考虑到材料的实际吸收及折射率随波长发生变化的情况 ,当n≥ 9时 ,该体系出现全反射带 (光子带隙 ) ,在 (Si SiO2 ) n 光子晶体中的SiO2 层的中间插入金属银层 ,构成 (Si SiO2 Ag SiO2 ) n 金属型一维光子晶体 ,光子带隙的宽度明显加宽 ,且在该带隙中s光和p光在 0— 6 0°入射角下均具有较低损耗 ,利用这一特性 ,可以制作出宽带反射镜 The effects of metal intercalation on the optical transmission properties of one-dimensional photonic crystals composed of Si-SiO2 have been investigated theoretically using the transfer matrix method. The results show that the one-dimensional photonic crystals composed of (Si SiO2) n, The actual absorption and refractive index changes with wavelength. When n ≥ 9, the system exhibits total reflection band (photonic bandgap), inserting a metallic silver layer in the middle of the SiO2 layer (Si SiO2) n photonic crystal, (Si SiO2 Ag SiO2) n metallic one-dimensional photonic crystal, the width of photonic band gap widens significantly, and in this band gap s light and p light at the incident angle of 0- 60 ° have a lower loss, the use of This feature, you can create a broadband reflector
