Abstract
We investigate the spontaneous emission rate γ of dipolar excitons in molecular crystal slabs of variable thickness, L, ranging from monolayers to bulk crystals. We find a smooth transition between superradiant excitons (γ ∝ L) at thickness small compared to an optical wavelength (λ) and radiatively stable polaritons for thick crystals (γ ∝ 1/L). The maximum cooperativity volume of the molecules in the slab is found to be of the order λ^3.
