Abstract

Abstract Nowadays active light-emitting dielectric nanophotonics is one of the most rapidly developing research field. These nanosystems make possible to direct emission of a light source placed inside nanoantenna in the specific direction with low-losses. Here we study the application of silicon for the creation of active all-dielectric nanoantenna emitting at the telecommunication wavelength (1540 nm). We numerically calculate Purcell factor in silicon nanoparticles (spherical and cylindrical) and demonstrate that in these nanostructures Purcell factor value can be enhanced by two orders of magnitude for this wavelength. The obtained data can be applied for the creation of active silicon nanoantenna doped with erbium for perspective light emitting metasurfaces.
