Existence loci of bound states in the continuum in the parameter space of anisotropic planar structures
(Optical Society of American (OSA), 2019)
Conference lecture
Open AccessBound 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 ... -
Waveguide stopped light mediated by mode transitions
(Optical Society of American (OSA), 2019)
Conference lecture
Open AccessHyperbolic metamaterials (HMMs) are uniaxial materials that have hyperbolic dispersion curves. There are two types of hyperbolic metamaterials, type I that is described by a permittivity tensor with e|| < 0 and e¿ > 0, and ... -
Angular control of anisotropy-induced bound states in the continuum
(2019-11-01)
Article
Open AccessRadiation 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 ... -
Water splitting for hydrogen chemisorption in graphene oxide dynamically evolving to a graphane character lattice
(2019-11-01)
Article
Restricted access - publisher's policyGraphane offers a safe and high capacity hydrogen storage. Unfortunately, production of graphane directly from its parent material graphene requires breaking the extended p bond, implying either harsh chemical environments ... -
Inverse Optical Cavity Design for Ultrabroadband Light Absorption Beyond the Conventional Limit in Low-Bandgap Nonfullerene Acceptor–Based Solar Cells
(2019-05-23)
Article
Open AccessIn the subwavelength regime, several nanophotonic configurations have been proposed to overcome the conventional light trapping or light absorption enhancement limit in solar cells also known as the Yablonovitch limit. It ... -
Formamidinium Incorporation into Compact Lead Iodide for Low Band Gap Perovskite Solar Cells with Open-Circuit Voltage Approaching the Radiative Limit
(2019-03-06)
Article
Open AccessTo bring hybrid lead halide perovskite solar cells toward the Shockley-Queisser limit requires lowering the band gap while simultaneously increasing the open-circuit voltage. This, to some extent divergent objective, may ...
