If a layer of cyanine dye J‐aggregates is placed in an optical cavity, interactions between the confi ned optical fi eld and the molecular excitons leads to the formation of cavity polaritons. On page 3691 , David G. Lidzey and co‐workers present vibrationally assisted polariton relaxation in strongly coupled organic semiconductor microcavities. The population of polaritons from uncoupled excitons that are initially generated following non‐resonant excitation is mediated by interactions with the Raman‐active molecular vibrations of the cyanine dye.
