Numerical model of the inhomogeneous scattering by the human lens
A Cuadrado, LM Sanchez-Brea, FJ Torcal-Milla +2
We present in this work a numerical model for characterizing the scattering properties of the human lens. After analyzing the scattering properties of two main scattering particles…
Slow thermo-optomechanical pulsations in suspended 1D photonic crystal nanocavities
Piergiacomo Z. G. Fonseca, Irene Alda, Francesco Marino +4
We investigate the nonlinear optical response of suspended 1D photonic crystal nanocavities fabricated on a silicon nitride chip. Strong thermo-optical nonlinearities are demonstra…
Plasmonic sensors based on funneling light through nanophotonic structures
Mahmoud H. Elshorbagy, Alexander Cuadrado, Javier Alda
We present a refractometric sensor realized as a stack of metallic gratings with subwavelength features and embedded within a low-index dielectric medium. Light is strongly confine…
Ultra-narrow spectral response of a hybrid plasmonic-grating sensor
Mahmoud H. Elshorbagy, Alexander Cuadrado, Braulio Garcia-Camara +3
We configure and analyze a nanostructured device that hybridizes grating modes and surface plasmon resonances. The model uses an effective index of refraction that considers the vo…
Performance improvement of refractometric sensors through hybrid plasmonic-Fano resonances
Elshorbagy, M., Cuadrado +6
In this paper, we present a plasmonic refractometric sensor that works under normal incidence; allowing its integration on a fiber tip. The sensor's material and geometry exploit t…
Polaritonic-to-Plasmonic Transition in Optically Resonant Bismuth Nanospheres for High-Contrast Switchable Ultraviolet Meta-Filters
Alexander Cuadrado, Johann Toudert, Rosalia Serna
In the quest aimed at unveiling alternative plasmonic elements overcoming noble metals for selected applications in photonics, we investigate by numerical simulations the near ultr…
