摘要

采用三维有限元法对亚波长光栅波导进行了数值分析。研究了波导的核心高度、宽度、占空比和折射率对比度等参数的变化及其影响。色散关系得到了40THz量级的频移。

Characterization of subwavelength grating waveguides with 3D finite element method

A subwavelength grating waveguide was numerically analyzed by a 3D finite element method. Waveguide parameters as core height, width, duty cycle, and index contrast were varied and its effects investigated. Frequency shifts of the order of 40THz were obtained for the dispersion relation.
