我们发现，染料掺杂聚合物开辟了一条在纳米尺度上控制光的有趣途径。就像众所周知的基于金属的等离子体系统一样，传播模和局域模都是可能的。我们表明，等离子体激子提供的吸引人的特性，特别是增强的光场和亚波长场限制，也适用于这些材料。因此，它们在纳米光子学中打开了一个新的机会，其中制造和功能可能通过利用分子和超分子化学来实现。
We show that dye-doped polymers open an interesting route to controlling light at the nanoscale. Just as for the much better known metal-based plasmonic systems, propagating and localized modes are possible. We show that the attractive features offered by plasmonics, specifically enhanced optical fields and subwavelength field confinement, are also available with these materials. They thus open a new opportunity in nanophotonics in which fabrication and functionality might be achieved by harnessing molecular and supramolecular chemistry.
