Multilayered Metal-Dielectric Structures for Control of Magnetic Dipole Emission

Metal-dielectric multilayers with nanoscale layer thickness exhibiting hyperbolic dispersion and infinite density of photonic modes, provide opportunities for modification and control of quantum processes in or in a close vicinity to such structures. In our work, we explore multilayered metal-dielectric structures for control of spontaneous emission of Eu3⁺ ions at the magnetic dipole transition. Using COMSOL software, we model the structure consisting of metal, dielectric and emitting layers, study its optical and plasmonic properties, and explore the possibility to selectively enhance or suppress magnetic and electric dipole emission. This possibility presents the special interest for Eu3⁺ organic systems where the electric dipole transitions are the main competitive channels for the magnetic dipole transition. Theoretical results are compared with the experiment.
