Splitting and Filtering Properties of Defect-Mode in One-Dimensional Photonic Crystal

Abstract:

By the Transfer Matrix Method (TMM), the properties of defect modes, such as splitting, coupling and filtering, have been researched in detail. The influence of refractive index and incident angle on the defect-mode coupling has been investigated. Simulating results exhibit that coupling mode split as two defect modes when they are close to each other. This property is closely related to the refractive index and the spacing interval between defect layers. The incident angle can reach 30 degree, which has a potential application in full angle filtering.
