Electromagnetic modeling of a silver nanostrip laser placed into an active cylinder

Recent progress in nanophotonics and nanoelectronics is greatly associated with understanding and use of resonance phenomena able to provide concentration of electromagnetic-wave power on nanoscale. This quest started quite long ago with the discovery of the localized surface plasmons (LSP) on metallic nanoparticles. Here, development of nanolasers based on LSP is important in the context of source light miniaturization for advanced nanophotonic and optoelectronic applications [1].
