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…
