Phys. Rev. Lett. 97, 045501 (2006) [4 pages]Phonon-Induced Polariton SuperlatticesReceived 15 February 2006; published 24 July 2006 We show that the coherent interaction between microcavity polaritons and externally stimulated acoustic phonons forms a tunable polariton superlattice with a folded energy dispersion determined by the phonon population and wavelength. Under high phonon concentration, the strong confinement of the optical and excitonic polariton components in the phonon potential creates weakly coupled polariton wires with a virtually flat energy dispersion. © 2006 The American Physical Society URL:
