非线性等离子体缝隙波导

Nonlinear plasmonic slot waveguides

A. R. Davoyan, I. V. Shadrivov, Yu. S. Kivshar

摘要:

本文研究了夹在两种金属之间的非线性介质平板所产生的亚波长缝隙波导中的非线性模。我们给出了非线性等离子体激元模族的色散图,并揭示了对称模经历了能量主要集中在其中一个界面附近的破缺分叉。我们还发现,反对称模可以分裂成两个分支,产生两族非线性反对称模。

英文摘要:

We study nonlinear modes in subwavelength slot waveguides created by a nonlinear dielectric slab sandwiched between two metals. We present the dispersion diagrams of the families of nonlinear plasmonic modes and reveal that the symmetric mode undergoes the symmetry-breaking bifurcation with the energy primarily localized near one of the interfaces. We also find that the antisymmetric mode may split into two brunches giving birth to two families of nonlinear antisymmetric modes.
