Strong coupling in an organic metal-clad microcavity

Summary form only given. The interaction between light and matter can be significantly altered by placing the material in an optical microcavity. Under appropriate conditions strong coupling may occur, a process in which the confined electromagnetic field of the microcavity dramatically modifies the optical transitions of the material, resulting in an anti-crossing (Rabi splitting) of the coupled modes of the microcavity. Recently strong coupling has been observed in organic materials including J-aggregates of cyanine dyes. They have the desired properties of large oscillator strength and narrow linewidth, and have shown large Rabi splitting at room temperature. We report here significant strong coupling in a new structure, a metal clad organic microcavity.
