Leakage radiation spectroscopy has been applied to study surface plasmon polariton (SPP) generation by light scattered off aligned organic nanofibers deposited on a thin silver film. The efficiency of SPP generation was studied by angularly resolved leakage radiation spectroscopy as a function of excitation wavelength in the range 550–800 nm for both normal and oblique angles of incidence. For comparison, the differential transmission scattering cross section was calculated using Green’s function integral equations. Both theory and experiments show highly directional and much more efficient SPP excitation at an oblique angle of light incidence.
