Excitation and Detection of Surface Exciton Polaritons by Optical Nonlinear Mixing

Abstract

Theoretical studies on nonlinear excitation and detection of surface exciton polaritons (SEP) by optical mixing are presented, taking into account the spatial dispersion effect. Numerically estimated power of the signal indicates that such a nonlinear effect allows us to obtain characteristics of SEP for an air-SEP active material geometry. Moreover, it can be expected that though the scattered intensity is considerably weak, it is detectable.
