Microcavity exciton-polariton splitting in the linear regime

Abstract
Comparisons are made of a classical and a quantum mechanical model of polariton energy splitting inside a microcavity in the linear excitation regime. Analytical expressions are obtained for the splitting energy as a function of temperature, detuning, and exciton-photon coupling constants. Experimental results are compared with theory, and agreements are found only if the effect of inhomogeneity is taken into account.
