The present work is devoted to the development of effective approach for the control of the optical properties of photonic nanostructures. Recently, certain efforts were addressed to the modification of spontaneous emission of various quantum dots by the resonant coupling with surface plasmons localized in metal nanoparticles. However, the efficiency of such coupling is limited by the short interaction distance of localized plasmons, which is usually in the range of several nanometers. In contrast in our study we focus on longer range propagating surface plasmon polaritons and quasi-waveguide modes as promoters for the quantum dots luminescence enhancement. Namely, modulation of luminescence of silicon nanocrystals in a solid matrix was studied since such structures are considered to be promising for optoelectronics and solar cells applications.
