窄带多通道滤光片的设计与制备

介绍了三种获得窄带多通道滤光片的方法。第一种方法是具有缺陷的多异质结结构，该结构能够展宽光子晶体的禁带同时实现多通道效应。第二种方法是多通道导模共振布儒斯特滤光片，此类滤光片可以采用单层膜结构来实现多通道效应，也可以采用具有相等折射率的双层膜结构来实现多通道效应。第三种方法是组合刻蚀法制备窄带滤光片列阵。该方法不仅可以制作单腔窄带滤光片列阵，还可以制作双腔窄带滤光片列阵。窄带多通道滤光片在光学领域中具有一定的应用前景。

Design and fabrication of narrowband multichannel filters

Three proposed approaches are used to obtain narrowband multichannel filters . The first approach is using multiple heterostructures inserted with defects mode. The enlargement of the forbidden band and the realization of multiple channeled filtering can be reached simultaneously by using this method. The second approach is using guided-mode resonance Brewster filters with multiple channels. For this method, narrowband filters with multiple channels can not only be obtained by using single layer structure, but also be obtained by using double layer structure with equal refractive index. The third approach is integrated optical filter arrays using the combinatorial etching technique. Single and double chamber narrowband filter arrays can be both obtained by using this method. Narrowband multichannel filters obtained by using these three methods are potentially useful in many optical applications.
