Polarization dependent optical response of the periodicallynanostructuredSiO2-Ag nanocomposite material is investigated.As a result of the laser-based surface structuring, the reflection is found to be particularly enhanced and blueshifted for parallel polarisation. This result is attributed to the interaction between photonic and plasmonc resonances, namely to the coupling of the grating caused Rayleigh-Woodanomaly mode (described by using grating theory) with localized surface plasmon modes of the embedded Ag nanoparticles (described by using effective medium approach).The laser-induced formation of such metasurface allows precise control of the effect that is essential for practical application in photonics devices and optical filters
