Optimum design of permeable diffractive lenses based on photon sieves
Veronica Pastor-Villarrubia, Angela Soria-Garcia, Joaquin Andres-Porras +4
Photon sieves are permeable diffractive optical elements generated by open apertures on a substrate. These elements are well suited for the monitoring of running fluids. Our analys…
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…
