Unveiling Symmetry Protection of Bound States in the Continuum with Terahertz Near-field Imaging
Niels J. J. van Hoof, Diego R. Abujetas, Stan E. T. ter Huurne +4
Bound states in the continuum (BICs) represent a new paradigm in photonics due to the full suppression of radiation losses. However, this suppression has also hampered their direct…
Enhanced light emission by magnetic and electric resonances in dielectric metasurfaces
Shunsuke Murai, Gabriel W. Castellanos, T. V. Raziman +2
We demonstrate an enhanced emission of high quantum yield molecules coupled to dielectric metasurfaces formed by periodic arrays of polycrystalline silicon nanoparticles. Radiative…
Strong coupling between weakly guided semiconductor nanowire modes and an organic dye
Diego R. Abujetas, Johannes Feist, Francisco J. García-Vidal +2
The light-matter coupling between electromagnetic modes guided by a semiconductor nanowire and excitonic states of molecules localized in its surrounding media is studied from both…
Excitation of confined modes on particle arrays
Xesús Manoel Bendaña, Gabriel Lozano, Giuseppe Pirruccio +2
We describe both theoretically and experimentally the existence and excitation of confined modes in planar arrays of gold nanodisks. Ordered 2D lattices of monodispersive nanoparti…
