宽截止窄带滤光片设计
Design of Wide Stop-band and Narrow Pass-band Filters
摘要
介绍了一种获得窄带宽截止滤光片的方法,即具有缺陷的多异质结结构,这种结构能够展宽光子晶体的禁带同时实现窄通带效应。通带的位置与缺陷的厚度及缺陷的位置有关,设计的窄带宽截止滤光片在光学领域中具有一定的应用前景。
Abstract
One proposed approach using multiple heterostructures inserted with defects mode is used to obtain narrow pass-band and wide stop-band filters in this paper. The enlargement of the forbidden band and the realization of narrow pass-band filtering can be reached simultaneously by using this method. The pass-band is related to the thickness and the position of defects. Wide stop-band and narrow pass-band filters obtained by using this method are potential useful in many optical applications.
