Journal ArticleDOI
Multipolar lasing modes from topological corner states.
TL;DR: This work demonstrates lasing action of corner states in nanophotonic topological structures and identifies several multipole corner modes with distinct emission profiles via hyperspectral imaging and discern signatures of non-Hermitian radiative coupling of leaky topological states.
Journal ArticleDOI
Revisiting the physics of Fano resonances for nanoparticle oligomers
TL;DR: In this article, a robust approach for interpreting the physics of Fano resonances in planar oligomer structures of both metallic and dielectric nanoparticles is presented, and it is shown that such resonances can be generated purely from the interference of nonorthogonal collective eigenmodes, which are clearly identified based on the coupled-dipole approximation.
Journal ArticleDOI

TL;DR: An all-dielectric sensing platform based on silicon nanodisks with strong optically-induced magnetic resonances is demonstrated, able to detect a concentration of streptavidin of as low as 10-10 M (mol L-1) or 5 ng mL-1, thus pushing the current detection limit by at least two orders of magnitudes.
Journal ArticleDOI
Binary parity-time-symmetric nonlinear lattices with balanced gain and loss
TL;DR: It is demonstrated that such nonlinear binary lattices support stable discrete solitons, which can be adiabatically tuned and switched through nonlinear symmetry breaking by varying gain and loss parameters.

TL;DR: The findings show the possibilities for realizing efficient impedance-matched hyperbolic media for unpolarized light in three-dimensional metamaterials and demonstrate the strong enhancement of thermal emission, which becomes directional, coherent and polarized.
