研究了一种"光子晶体多层膜+波导层+光子晶体多层膜"对称薄膜的波导特性,光子晶体多层膜的第一禁带频率范围为73～99 THz.采用多层介质平板波导理论研究了频率在73～99 THz间的电磁波在波导中的传输特性.结果表明波导传输的是TE0和TM0基模,对于高次模式,不能在波导中传输,另外,频率在73～99 THz间的电磁波在波导层(中心层)的功率约束因子(Г)在0.99～1之间,即此时电磁波几乎完全局限在波导层内传输,为了比较,处在光子带隙外的频率分别为40 THz和50 THz的电磁波在波导层内的功率约束因子分别为0.84和0.86,因此,利用光子带隙特征,由光子晶体多层膜构造的对称薄膜波导具有超低损耗特性.
