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…
All-Optical Nanometric Switch based on the Directional Scattering of Semiconductor Nanoparticles
Braulio Garcia-Camara, J. Francisco Algorri, Alexander Cuadrado +4
A structure based on a dimer of silicon nanoparticles, presenting directional scattering in the visible range, was studied as a new design of an all-optical switch. The combination…
