通道等离子体激元-极化激元:模态形状、色散和损耗

Channel plasmon-polaritons: modal shape, dispersion, and losses

Esteban Moreno, F. J. Garcia-Vidal, Sergio G. Rodrigo, L. Martin-Moreno, Sergey I. Bozhevolnyi

摘要:

我们理论上研究了具有与最近在电信波长下的实验中的几何结构类似的几何结构的通道等离子体激元(CPP)(Bozhevolnyi等人,Nature 440,508(2006))。采用多重多极子法和时域有限差分法对CPP的模态振型、色散关系和损耗进行了数值模拟。结果表明,随着波长的增加,基本CPP模式逐步向凹槽开口移动,在凹槽底部停止被引导,并与沿凹槽边缘运行的楔形等离子体激元-极化激元杂交。

英文摘要:

We theoretically study channel plasmon-polaritons (CPPs) with a geometry similar to that in recent experiments at telecom wavelengths (Bozhevolnyi et al., Nature 440, 508 (2006)). The CPP modal shape, dispersion relation, and losses are simulated using the multiple multipole method and the finite difference time domain technique. It is shown that, with the increase of the wavelength, the fundamental CPP mode shifts progressively towards the groove opening, ceasing to be guided at the groove bottom and becoming hybridized with wedge plasmon-polaritons running along the groove edges.
