Elongation of Surface Plasmon Polariton Propagation Length Without Gain

Opt Express. 2008 Sep 29;16(20):15576-83. doi: 10.1364/oe.16.015576.

Abstract

We have demonstrated that an addition of highly concentrated rhodamine 6G chloride dye to the PMMA film adjacent to a silver film can cause 30% elongation of the propagation length of surface Plasmon polaritons (SPPs). The possibility to elongate the SPP propagation length without optical gain opens a new technological dimension to low-loss nanoplasmonic and metamaterials.
