【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.更多还原
