Abstract

An investigation of oblique plane-wave electromagnetic scattering from active dielectric films reveals the existence of anomalously large resonances that occur at discrete plane-wave angles of incidence. These resonances may be understood from a leaky-wave phase-matching condition whose predictions for the first few modes agree to within a few percent of those obtained from a rigorous treatment using Maxwell’s equations. Enhancement in the scattered-field intensities of the order of 100 was observed in experiments using finite-diameter pump and probe laser beams and active films as thin as 6 μm.
