摘要

采用有效频域有限元法分析了亚波长光栅波导的传播特性。得到了具有多个占空比和宽带宽的等效连续波导。通过重叠积分比较了它们的电场空间分布。等效连续波导可用于分析SWGs。

Propagation characteristics analysis of subwavelength grating waveguides

The propagation characteristics of a subwavelength grating (SWG) waveguide are analyzed by an efficient frequency domain finite element approach. An equivalent continuous waveguide has been obtained for several duty cycles and for a wide bandwidth. A comparison of their electric field spatial distribution has been performed through an overlapping integral. An equivalent continuous waveguide can be considered for the analysis of SWGs.
