  • Anisotropy-induced photonic bound states in the continuum 

    Gomis Bresco, Jordi; Artigas García, David; Torner Sabata, Lluís (Nature, 2017-03-20)
    Article
    Open Access
    Bound states in the continuum (BICs) are radiationless localized states embedded in the part of the parameter space that otherwise corresponds to radiative modes. Many decades after their original prediction1, 2, 3 and ...
  • Bound states in the continuum in anisotropic structures 

    Gomis Bresco, Jordi; Artigas García, David; Pujol Closa, Pilar; Torner Sabata, Lluís (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Restricted access - publisher's policy
    We report theoretical and experimental observation of radiationless bound states in the continuum (BIC) in waveguiding anisotropic structures. BICs may have all possible polarizations and be the only possible boundstates ...
  • Self-sustained coherent phonon generation in optomechanical cavities 

    Navarro Urios, D.; Gomis Bresco, Jordi; Alzina, F. (Institute of Physics (IOP), 2016-09)
    Article
    Open Access
    Optical forces can set tiny objects in states of mechanical self-sustained oscillation, spontaneously generating periodic signals by extracting power from steady sources. Miniaturized self-sustained coherent phonon sources ...
  • Topological properties of bound states in the continuum in geometries with broken anisotropy symmetry 

    Mukherjee, Samyobrata; Gomis Bresco, Jordi; Pujol Closa, Pilar; Artigas García, David; Torner Sabata, Lluís (2018-12-18)
    Article
    Open Access
    Waveguiding structures made of anisotropic media support bound states in the continuum (BICs) that arise when the radiation channel of otherwise semileaky modes is suppressed. Hitherto, only structures with optical axes ...
