The numerical aperture of the waveguide is matched to a single-mode fiber and the propagating loss of the waveguide is lower than a rectangular silicon waveguide. 这种光波导的数值孔径和单模光纤匹配,传播损耗低于平面条形硅光波导。
Transient finite element method hybridization with mode matched method is constructed for modeling discontinuous problem in waveguide. 在本论文中,研究模匹配与时域有限元法结合的混合方法,用于求解波导中不连续问题的时域解。
