Probing the transition from an uncoupled to a strong near-field coupled regime between bright and dark mode resonators in metasurfaces

Singh, Ranjan; Al-Naib, Ibraheem; Roy Chowdhury, Dibakar; Cong, L; Rockstuhl, Carsten; Zhang, Weili

Description

The coupling of multiple plasmonic resonators that sustain bright or dark modes provide intriguing spectral signatures. However, probing the onset of coupling effects while engaging the resonators with an increasing proximity has not yet been studied experimentally in detail. Nevertheless, this is of utmost importance to bridge the phenomenological understanding with the peculiarities of realworld-samples. Here, we take advantage of the ability to control spatial dimensions of THz metasurfaces...[Show more]
