基于双层金属光栅的中波红外多通道滤光片结构

Multi-channel mid-infrared filter structure based on bilayer metallic grating

  • 摘要: 提出一种多通道平面窄带滤光片阵列结构,该结构由双层金属光栅及其两侧的分布式布拉格反射器(DBRs)组成。所设计的多通道滤光片中心波长范围超过200 nm,每一个通道的中心波长可以通过调节光栅狭缝宽度来调节,从而实现多通道窄带滤光阵列。该结果为中波红外多通道窄带滤光片的设计提供了一条新的路径。

     

    Abstract: A planar array structure of multi-channel narrowband filter was proposed, which consisted of bilayer metallic grating and its bilateral distributed Bragg reflectors (DBRs). The central wavelength range of the designed multi-channel filter exceeded 200 nm, and the central wavelength of each channel could be adjusted by grating slit width to realize the multi-channel narrowband filter array. The results provides a new approach for designing the multi-channel mid-infrared narrowband filter.
