本文研究了导模谐振滤波器（GMRF）谐振时线宽与最大电场强度（MEFI）的关系。它表明，线宽将与MEFI成反比的GMRF的一些参数之一的增加（例如周期，厚度，和填充因子的GMRF和覆盖折射率的光栅），并与其他保持。研究还表明，随着GMRF中任一参数的增大，谐振波长将向长波方向移动。光栅的周期和厚度的变化与波长漂移有很好的线性关系。这将是光学传感器系统感兴趣的。
In this paper, relationship between linewidth and maximum electric field intensity (MEFI) at resonance of guided-mode resonance filter (GMRF) is investigated. It is demonstrated that the linewidth will vary inversely with the MEFI as one of some of the parameters of the GMRF increasing (e.g. period, thickness, and filling factor of the grating in the GMRF and cover refractive index) and with others maintained. Also it is demonstrated that resonant wavelength will shift to longer wavelength as any one of the parameters of the GMRF increasing. Moreover, the changes of period and thickness of grating have good linear relation with wavelength shifting. This will be of interest for optical sensor systems.
