In low density regime, the fluorescence of Frenkel exitons in crystal slab can be studied without the aid of rotating wave and Mackoffian approximation. The equations for the case of double and triple lattice-layers are now solved exactly to give the eigen decay rates, frequency shifts and the statistical properties of the fields.
The effect of the non-linear interaction between the high density Wannier excitons is analysed. We use the Fokker-Planck equation in the positive P presentation and the corresponding stochastic differential equation to study the composite system of a single mode cavity field and exciton under classical field pumping. The small fluctuation approximation is made to get the quadrature squeezing spectra of the output light field. The conditions for the squeezing of the either quadrature component of the output light are given.
