高性能硅光子滤波器：基于非对称多模亚波长光栅的实现

///'A novel silicon photonic filter is proposed and demonstrated to have exceptional performance through the use of apodized antisymmetric multimode subwavelength gratings (MSWGs) structures. The MSWGs allow for index engineering within the Bragg lattice, enabling flexible manipulation of the coupling coefficient, local effective index, and mode profile. Consequently, the filter effectively suppresses strong side lobes, while also allowing for flexible bandwidth design and a free spectral range (FSR). These features make the filter highly attractive and useful for a wide range of applications.///
