The Scattering of Light from Surface Polaritons: Line Intensities and Line Shapes
In this paper, we present a summary of our recent work on the theory of light scattering from surface polaritons. The emphasis is placed on contact with the results of Ushioda et al, who have observed surface polaritons in the Raman spectrum of light forward-scattered from a GaAs film on a sapphire substrate, with the laser beam incident through the substrate. The theory accounts very well for the relative intensity of the surface polariton peaks in the near forward direction, the large forward/backward asymmetry in the cross section, and the shapes of the structures observed in the Raman spectrum.
