Polariton‐Mediated Energy Transfer in a Tunable Optical Multimode Microcavity Exceeding 10 μm
Abstract
Energy transfer between a donor‐acceptor pair of J‐aggregated dyes, which are spin‐coated onto the mirrors of a tunable Fabry–Pérot microresonator, is studied. It is found that both donor and acceptor are strongly coupled to the optical modes of the resonator and form hybrid light–matter states (polaritons). The shapes of the fluorescence spectra show efficient energy transfer from donor to acceptor, which are separated up to 11 μm. Within the same measurement, the energy transfer efficiency appears to be independent of donor–acceptor separation. The observed fluorescence features are well explained by a phenomenological Hamiltonian, which models the emerging polariton modes and rate equations.
