本文研究了单层膜多模导模共振滤光片的电场增强效应.单层膜导模共振滤光片同时兼具波导和相位匹配功能的物理机制得到了论证.当光栅厚度不断增加将出现多模共振效应,导致高阶泄漏模电场增强效应的产生.电场增强振幅的最大值反映导模共振滤光片的泄漏程度.通常在同一共振位置处电场增强振幅的最大值越大,其带宽就越小.

Electric field enhancement in single layer multimode guided-mode resonance filters(GMRFs)is presented.The physical basis that a single layer GMRF can be functioned simultaneously as the waveguide and the phase matching element is demonstrated.Multimode resonance occurs as the grating thickness increases,resulting in electric field enhancement of high order leaky modes.The order of the electric field of maximum amplitude indicates the leakage level of the GMRFs.Thus the bigger maximum amplitude of the electric field will generally correspond to the smaller filter linewidth at the same resonance wavelength.
