The enhanced exciton−plasmon coupling creates a Fano like line shape in the differential reflection spectra associated with the formation of hybrid states, leading to anti-crossing of the upper and lower polaritons with a Rabi frequency of 125 meV. The recreation of a Fano like line shape was found in photoluminescence demonstrating changes in the emission spectral profile under strong coupling.enThe following article appeared in Applied Physics Letters, 108(5) and may be found at http://link.aip.org/link/doi/10.1063/1.4941078.
