Generation of nearly pure and highly directional magnetic light in fluorescence of rare earth ions
Anton D. Utyushev, Roman Gaponenko, Song Sun +3
A thorough analysis of the emission via the magnetic dipole (MD) transition, called magnetic light below, of trivalent rare-earth ions in or near dielectric homogeneous spheres has…
Experimental demonstration of superdirective spherical dielectric antenna
Roman Gaponenko, Mikhail S. Sidorenko, Dmitry Zhirihin +5
An experimental demonstration of directivities exceeding the fundamental Kildal limit, a phenomenon called superdirectivity, is provided for spherical high-index dielectric antenna…
Metal-Dielectric-Enhanced Upconversion: Going "Meso"
Ilia L. Rasskazov, Alexander Moroz, Catherine J. Murphy +2
A novel concept of a \textit{mesocavity}, based on a simple yet counter-intuitive idea of covering metal nanoparticles with unusually thick ( nm) high-index dielectric…
