Unidirectional guided resonances in anisotropic waveguides
Samyobrata Mukherjee, Jordi Gomis-Bresco, David Artigas +1
We show that anisotropic planar anti-guiding waveguide structures with two radiation channels towards the surrounding cladding materials can support unidirectional guided resonance…
Quantifying the robustness of topological slow light
Guillermo Arregui, Jordi Gomis-Bresco, Clivia Marfa Sotomayor-Torres +1
Low-dimensional nanostructured materials can guide light propagating with very low group velocity vg. However, this slow light is significantly sensitive to unwanted imperfections…
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,…
Transition from Dirac points to exceptional points in anisotropic waveguides
Jordi Gomis-Bresco, David Artigas, Lluis Torner
We uncover the existence of Dirac and exceptional points in waveguides made of anisotropic materials, and study the transition between them. Dirac points in the dispersion diagram…
Anisotropy-induced photonic bound states in the continuum
Jordi Gomis-Bresco, David Artigas, Lluis Torner
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 afte…
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…
