Abstract:

Thin films of polyelectrolyte/J aggregate dye bilayers with high absorption coefficient (6 nm thick with alpha approximately equal to 1.0 x
10(6) cm(-1)) inserted in an optical microcavity enable the cavity quantum
electrodynamic strong coupling limit to be reached at room temperature
with a coupling strength (Rabi splitting) of 265 +/- 15 meV. By embedding
these films in a resonant cavity organic LED structure, we demonstrate the
first emissive electrically pumped exciton-polariton device.
