Abstract

I predict that a nanoscopic, high-permittivity layer on the surface of a plasmonic metal can cause total external reflection of surface plasmon polaritons (SPPs). Such a layer can be used as a mirror in nanoplasmonics, in particular for resonators of nanolasers and spasers and can also be used in adiabatic nanooptics. I also show that the earlier predicted slow propagating SPP modes, especially those with negative refraction, are highly damped.

摘要

我预测，等离激元金属表面的纳米级、高介电常数层可导致表面等离激元极化激元（SPP）的全外反射。这样的一层可在纳米等离激元学中用作镜子，特别是用于纳米激光器和受激辐射放大的自发辐射源（spaser）的谐振器，也可用于绝热纳米光学。我还表明，较早前预测的慢传播SPP模式，尤其是那些具有负折射的模式，具有高度的阻尼。
