Study of optical properties of plasmonic nanostructures for coherent emission generation and absorbers

Recent years fast progress in plasmonics promises advances and new developments in nano-optic, nanophotonics and metamaterials. However, high losses in the metals is still challenging goal for novel applications related with plasmonics. Strong coupling effect between plasmon and emitter can substantially reduce the losses of plasmonic waves. Planar multi-layered structures as well as structures which supports plasmonic surface lattice resonances can overcome this disadvantages. The structures mentioned above distinguished advanced features such as very narrow width and high quality of the resonances, singularities of the light phase, electric field enhancement, etc. Such kind of structures will be applied for new kind of coherent light sources based on plasmonic effect (lasing) and for the perfect absorbers. During this Ph.D. study there is an option partially to conduct our study in the Swinburne University of Technology (Australia) (supervisor prof. dr. S. Juodkazis) and also to graduate Ph.D.
