基于亚波长光栅衰减模态滤波器的设计与研究
The Design and Study of Filter Based on Evanescent Mode of Subwavelength Grating
摘要
Abstract
The characteristic equations of the effective refractive index function are obtained by the rigorous vector modal theory.The relationship between the modal characteristics and filling ratio as well as the normalized subwavelength grating constant is investigated, and the attenuation condition and characteristics of the attenuation mode are given.A high-pass filter is designed by the characteristics of the attenuation mode under the condition of Littrow-mounting incidence, and the response curve of the reflectivity with the wavelength is given.And a bandpass filter is designed by two gratings based on appropriate parameters.Our result is important for the experimental research and application of high-pass or bandpass filter and the subwavelength grating device.关键词
