Abstract
Recent work on the exciton-photon coupling is presented. The proposed structure is a two-coupled semiconductor microcavity, composed of distributed Bragg reflectors, each consists of Si3N4  /  SiO2, AlAs  /  Al0.1Ga0.9As, and GaAs/AlAs. Assuming that armchair graphene nanoribbon is located in the maximum of electric field amplitude inside the first semiconductor microcavity, the transfer matrix method is used to obtain the upper and lower polariton (UP and LP) branches and angle-dependent reflectance spectrum. A clear anticrossing between the neutral excitons and the cavity modes is observed for different polarization states. The obtained magnitude of splitting from the results is 10 to 12 meV, which indicates the possibility of enhancing the vacuum Rabi splitting for the proposed structure. This can pave the ways toward implementation of graphene in polaritonic devices.
