全圆锥入射下基于一维共振波导光栅的入射角调谐滤波器
Incident angle-tuned filter based on 1D resonant waveguide grating in full conical mounting
摘要
Abstract
This paper proposes and demonstrates a tunable filter using full conical mounting.The designed 1D resonant waveguide grating presents a tunable single reflection peak.The peak reflectance can theoretic-ally reach 100%.The resonant wavelength can be tuned from 642.5 nm to 484.6 nm by changing the incident angle.The resonance between the 1st-order diffracted wave and fundamental transverse electric(TE)guided mode generates the reflection peak.This feature was achieved by optimizing the grating thickness to support the TE guided mode and suppress the transverse magnetic(TM)guided mode.The same concept can be ap-plied to tunable filters with high dynamic range by increasing the thickness and period of grating in equal proportion.关键词
