  We propose a new model to implement organic exciton-semiconductor exciton
hybridization by embedding a semiconductor quantum dot array into an organic
medium. A Wannier-Mott transfer exciton is formed when the exciton in each
semiconductor dot interacts via the multipole-multipole coupling with other
excitons in the different dtos of the array. A new hybrid exciton appears in
the system owing to strong dipole-dipole interaction of the Frenkel exciton of
the organic molecules with the Wannier Mott transfer exciton of the quantum dot
array. This hybrid exciton has both a large oscillator strength (Frenkel like)
and a large Bohr radius (Wannier like). At resonance between these two types of
excitons, the optical non-linearity is very large and can be controlled by
changing parameters of the system such as dot radius and dot spacing.
