Abstract

We studied dispersion in Rhodamine laser dyes in the Kretschmann geometry and found (i) multi-branch “staircase” dispersion curves in singly doped and double doped PMMA polymer, (ii) emergence of the new dispersion “fork” branch, (iii) unparallel dispersion and coupling in the mixture of two different dyes, and (iv) effect of high dye concentration on strong coupling without metal.

耦合表面等离子体和激子中的反常色散

我们研究了罗丹明激光染料在Kretschmann几何中的色散，发现(i)单掺杂和双掺杂PMMA聚合物中的多分支“阶梯”色散曲线，（ii）新的色散“叉”分支的出现，（iii）两种不同染料混合物中的非平行色散和耦合，以及（iv）高染料浓度对无金属强耦合的影响。
