2-DIMENSIONAL EXCITON POLARITONS IN MICROCAVITIES WITH EMBEDDED QUANTUM WIRES

Optical anisotropy of the periodical array of quantum wires embedded i n a semiconductor microcavity is shown to result in polarization-depen dent vacuum-held Rabi-splitting and a triple-anticrossing shape of the exciton-polariton dispersion curves. Both effects originate from the resonant diffraction of light at the grating of quantum wires. The cal culation has been done within the nonlocal dielectric response theory and using the 4 x 4 transfer matrix technique. (C) 1998 Academic Press Limited.
