We report ultra-compact surface-normal high-Q optical filters based on single- and double-layer stacked Fano resonance photonic crystal slabs on both Si and quartz substrates. A single layer photonic crystal filter was designed and a Q factor of 1,737 was obtained with 23 dB extinction ratio. With stacked double-layer photonic crystal configuration, the optical filter Q can increase to over 10,000,000 in design. Double-layer filters with quality factor of 9,734 and extinction ratio of 8 dB were experimentally demonstrated, for a filter design with target Q of 22,000.
我们报道了基于硅和石英衬底上的单层和双层堆叠法诺共振光子晶体平板的超紧凑型垂直表面高Q值光学滤波器。设计了一种单层光子晶体滤波器，获得了品质因数为1737、消光比为23 dB的结果。采用双层光子晶体堆叠结构，在设计中光学滤波器的品质因数可提高到10000000以上。实验展示了品质因数为9734、消光比为8 dB的双层滤波器，其目标品质因数设计为22000。
