Fabrication and characterization of silver mirror planar microcavity with dye J-aggregates

Silver mirror planar microcavity containing dye J-aggregates is fabricated by a vacuum deposition method. Characterization of the microcavity with the dye J-aggregates of lower concentration (7.70×10−4 M) in comparison with the previous studies is performed. Optical strong coupling between excitons and confined photons within the microcavity is demonstrated from the anticrossing of exciton and photon modes. Angle-resolved transmission measurements give a Rabi-splitting energy of ~190 meV for the upper and lower polariton splitting. The fabrication of such a simple metal-mirror-based microcavity (Q-factor ~13) leads to a progress of polaritonic characterization of organic media.
