Abstract

The dispersions and radiative decay rates of polaritons in self-assembling quantum wires have been investigated. This study is based on the analytical solution of the Maxwell's equations in a system presenting a lateral modulated dielectric constant and described by nonlocal periodically susceptibilities. With this generalized theoretical method, we can obtain the polariton energies and their radiative decay rates for any angle θ of incidence. The electromagnetic field confinement along two direction induces guided and diffracted modes which couple to one-dimensional excitonic modes. These interactions enhance strongly the polariton behavior in both S and P polarisations. In addition we have analysed the polariton radiative decay rates where the superlattice of quantum wires SQWW is considered as a resonator.
