Dirac Points Embedded in the Continuum
Pilar Pujol-Closa, Lluis Torner, David Artigas
Dirac points (DP) in Hermitian systems play a key role in topological phenomena. Their existence in non-Hermitian systems is then desirable, but the addition of loss or gain transf…
Slow light mediated by mode topological transitions in hyperbolic waveguides
Pilar Pujol-Closa, Jordi Gomis-Bresco, Samyobrata Mukherjee +3
We show that symmetric planar waveguides made of a film composed of a type II hyperbolic metamaterial, where the optical axis (OA) lays parallel to the waveguide interfaces, result…
Angular Control of Anisotropy-Induced Bound States in the Continuum
Samyobrata Mukherjee, Jordi Gomis-Bresco, Pilar Pujol-Closa +2
Radiation of leaky modes existing in anisotropic waveguides can be cancelled by destructive interference at special propagation directions relative to the optical axis orientation,…
Topological properties of bound-states-in-the-continuum in geometries with broken anisotropy-symmetry
Samyobrata Mukherjee, Jordi Gomis-Bresco, Pilar Pujol-Closa +2
Waveguiding structures made of anisotropic media support bound states in the continuum (BICs) that arise when the radiation channel of otherwise semi-leaky modes is suppressed. Hit…
