Abstract

The method of fitting the microcavity transmission spectrum to derive the cavity absorption spectrum by means of transfer-matrix analysis was flawed. Consequently, in contrast to our initial conclusions, the polaritonic emission appears thermalized and there is no evidence for polariton emission that is blue-shifted with respect to the polariton absorption. For this reason, the interpretation of the blue-shift as a signature of polariton-polariton interactions is obsolete. Two errors have been made: First, the dielectric function of PMMA was only modeled in the range from 1400 to 2100 cm-1 (original Figure 2(b)). However, by virtue of the Kramers-Kronig relations, the relatively strong absor..
