All-dielectric multi-resonant bullseye antennas

open access: yesOptics Express, 2022
Integrated devices that generate multiple optical resonances in the same volume can enhance on-chip nonlinear frequency generation, nonlinear spectroscopy, and quantum sensing. Here, we demonstrate circular Bragg antennas that exhibit multiple spatially overlapping, polarization-selective optical resonances.

Enhanced transmission of electromagnetic waves through split-ring resonator-shaped apertures [PDF]

open access: yes, 2011
The design of aperture shape is a promising approach for enhanced transmission through a subwavelength aperture. We designed split-ring-resonator (SRR)-shaped apertures in order to increase the transmission through subwavelength apertures by making use ...
