TL;DR: This work presents active optical control of metamaterial-induced transparency through active tuning of the dark mode, and opens up the possibility for designing novel chip-scale ultrafast devices that would find utility in optical buffering and terahertz active filtering.

TL;DR: In this article, the authors observe the excitation and tuning of electromagnetically induced transparency (EIT) by the interference between different excitation pathways of the dark mode in a planar terahertz metamaterial.

TL;DR: In this paper, the authors investigate the impact of the plasmonic interaction on the third-harmonic generation from a system of film-coupled nanostripes operating at 1500 nm.

TL;DR: In this article, the spectral properties of film-coupled plasmon-resonant, gold nanoparticles with dielectric spacer layers fabricated either using atomic layer deposition or using organic layers (polyelectrolytes or self-assembled monolayers of molecules).

TL;DR: A novel 3D imaging system is conceived based on 'phaseless' and compressed measurements, with benefits from recent advances in the field of phase retrieval, and a comparison of the estimated images from both complex valued and phaseless measurements is presented, verifying the fidelity of Phaseless computational imaging.
