摘要：

We discuss the linear and nonlinear optical properties of organic-inorganic nanostructures (quantum wells and superlattices) brought about by resonance interactions between Frenkel excitons in organic QWs and Wannier-Mott excitons in semiconductor QWs. We show that such a coupling (Coulomb dipole-dipole at an interface and through the cavity photons in a microcavity) is responsible for the appearance of mixed Frenkel-Wannier excitations. We demonstrate that the new hybrid states and their dispersion curves can be tailored to engineer the enhancement of resonant optical nonlinearity, fluorescence efficiency and relaxation processes.
