Anomalous dispersion in coupled surface plasmons and excitons
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.
