Light manipulation has been widely employed in lighting, display, and energy storage,
becoming an inseparable part of human lives. However, the conventional optical devices …

Scattering of electromagnetic waves by an arbitrary nanoscale object can be characterized
by a multipole decomposition of the electromagnetic field that allows one to describe the …

We study in detail a novel type of optical nanoantennas made of high-permittivity low-loss
dielectric particles. In addition to the electric resonances, the dielectric particles exhibit very …

Controlling light emission from quantum emitters has important applications, ranging from
solid-state lighting and displays to nanoscale single-photon sources. Optical antennas have …

By directing light, optical antennas can enhance light–matter interaction and improve the
efficiency of nanophotonic devices. Here we exploit the interference among the electric …

Dielectric particles supporting both magnetic and electric Mie resonances are shown to be
able to either reflect or collect the light emitted by a single photon source. An analytical …

We introduce the novel concept of superdirective nanoantennas based on the excitation of
higher-order magnetic multipole moments in subwavelength dielectric nanoparticles. Our …

Thanks to their enhanced and confined optical near-fields, broadband subwavelength
resonators have the ability to enhance the spontaneous emission rate and brightness of …

A photon interacts efficiently with an atom when its frequency corresponds exactly to the
energy between two eigenstates. But at the nanoscale, homogeneous and inhomogeneous …

Locally routing the exciton emissions in two-dimensional (2D) transition-metal
dichalcogenides along different directions at the nanophotonic interface is of great interest in …
