We study the optical properties of hybrid nanostructures comprising self-assembled InGaAs quantum dots (QDs) located in the direct vicinity from the surface which is covered with Au grating. The Au period is optimized in oder to support the excitation of surface plasmon polaritons (SPP) by excitons in QDs emission and vice versa. Angle dependent transmission and reflection spectra show clear signatures of SPP resonances. We investigate SPP influence on exciton dynamics measured by means of time-resolved photoluminescence.
