方位角调谐的反射窄带导模共振滤光片设计
Design of Guided Mode Resonant Filters Tuned by Azimuthal Angle
摘要
调谐反射窄带滤光片在光通信、显示、光开关和防伪等领域有重要应用。导模共振滤光片(GMRF)对结构参数非常敏感,因此可通过结构参数的变化来实现反射峰值的调谐。为了研究利用方位角的变化来实现导模共振滤光片调谐的新方法,分析了方位角对导模共振滤光片衍射区域电场分布的影响,通过严格的耦合波理论计算,设计了方位角调谐的导模共振滤光片。对于60°入射的TM偏振光,随着方位角的增加,导模共振滤光片的共振峰值向长波方向移动。
Abstract
Tunable reflective narrow filters have important applications in optical communication,display,optical switch,security images label and other fields. The design of narrow tunable reflective guide mode resonant filters (GMRF) using the variation of azimuthal angles was done. Through rigorous coupled-wave analysis,the structure of guided mode resonant filters whose reflective peak value depend on the azimuthal angle was obtained. For TM polarize light with 60° incident angle,the resonant peak value of guided mode resonant filters shifted to longer wavelength with the increase of azimuthal angles.
