摘要

研究了具有一维和二维周期性和不同对称性的光栅结构，以激发基于掺杂硅的SPP模式。结果表明，当掺杂浓度为1×1021cm-3时，在正入射条件下，优化后的六方对称圆形单元格光栅可以获得全吸光度。

Using an optimized grating as a mid-IR surface plasmon gas sensor utilizing highly doped silicon

Grating structures with 1D and 2D periodicity and different symmetry are investigated to excite an SPP mode based on doped silicon. It was found that total absorptance can be achieved by an optimized grating with hexagonal symmetry and circle unit cell under normal incidence for a doping concentration of 1×1021cm-3.
