Probing Azimuthal Anatomy of Hyperbolic Whispering Gallery Modes in hBN
Bogdan Borodin, Samyobrata Mukherjee, Shivaksh Rawat +8
Scattering-type scanning near-field optical microscopy (s-SNOM) is a powerful tool for investigating polaritonic modes. However, an inherent limitation of this technique is that ex…
Generation and Enhancement of Persistent Nanoscale Magnetization in All-Dielectric Metasurfaces by Optically Injected and Localized Free Carriers
Shivaksh Rawat, Samyobrata Mukherjee, Gennady Shvets
Time-varying dielectric metasurfaces that support sharp optical resonances with nontrivial electromagnetic field distributions constitute a unique platform for realizing temporal i…
Co-existing topological and Volkov-Pankratov plasmonic edge states in magnetized graphene
Samyobrata Mukherjee, Viktoriia Savchuk, Jeffery W. Allen +2
Graphene placed in a perpendicular magnetic field supports optical modes known as magnetoplasmons which are transversally confined to the graphene layer. Unlike ordinary graphene p…
Surface Bound States in the Continuum in Dyakonov Structures
Samyobrata Mukherjee, David Artigas, Lluis Torner
Surface bound states in the continuum (SBICs) have been found to occur in diverse settings, but so far always at the interface of non-homogeneous media, such as discrete lattices o…
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…
Solitary Spectrally-Discrete Bound States in the Continuum in an Open System
Samyobrata Mukherjee, Jordi Gomis-Bresco, David Artigas +1
Bound states in the continuum (BICs) exist in a variety of physical systems where they appear as lossless propagating states surrounded by radiating modes. However, in the case of…
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…
Transverse spin with coupled plasmons
Samyobrata Mukherjee, A V Gopal, S Dutta Gupta
We study theoretically the transverse spin associated with the eigenmodes of a thin metal film embedded in a dielectric. We show that the transverse spin has a direct dependence on…
Coherent perfect absorption mediated enhancement of transverse spin in a gap plasmon guide
Samyobrata Mukherjee, S. Dutta Gupta
We consider a symmetric gap plasmon guide (a folded Kretschmann configuration) supporting both symmeric and antisymmetric coupled surface plasmons. We calculate the transverse spin…
