Abstract: The effects of enhancement of stimulated Raman scattering in titanium oxynitride (TiON) nanofilms are considered. The mechanism of giant amplification of a Stokes wave is based on, first, localized plasmon resonance in titanium nitride (TiN) nanoparticles and, second, a spectrally degenerate behavior of the real part of the dielectric constant of the nanocomposite film. The enhancement of stimulated Raman scattering in the TiON film by means of a plasmonic nanoantenna and a nanostructured surface of the TiON film is demonstrated experimentally.
