    • Angular control of anisotropy-induced bound states in the continuum 

      Mukherjee, Samyobrata; Gomis Bresco, Jordi; Pujol Closa, Maria del Pilar; Artigas García, David; Torner Sabata, Lluís (2019-11-01)
      Article
      Open Access
      Radiation of leaky modes existing in anisotropic waveguides can be cancelled by destructive interference at special propagation directions relative to the optical axis orientation, resulting in fully bound states surrounded ...
    • Existence loci of bound states in the continuum in the parameter space of anisotropic planar structures 

      Mukherjee, Samyobrata; Gomis Bresco, Jordi; Pujol Closa, Maria del Pilar; Artigas García, David; Torner Sabata, Lluís (Optical Society of American (OSA), 2019)
      Conference lecture
      Open Access
      Bound states in the continuum (BICs), first predicted in the field of quantum physics [1], are localized radiationless states existing in the part of the spectrum that corresponds to radiative modes. BICs are a general ...
    • Topological properties of bound states in the continuum in geometries with broken anisotropy symmetry 

      Mukherjee, Samyobrata; Gomis Bresco, Jordi; Pujol Closa, Maria del 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 ...
    • Topology Transitions of Anisotropy Induced Bound States in the Continuum 

      Mukherjee, Samyobrata; Gomis Bresco, Jordi; Pujol Closa, Maria del Pilar; Artigas García, David; Torner Sabata, Lluís (2018)
      Conference report
      Open Access
      We demonstrate that Bound states In the Continuum (BICs) are supported in planar anisotropic structures where the optic axes are arbitrarily oriented. Moreover, we reveal fundamental new topological properties of these ...
