Grating-Coupling-Based Excitation of Bloch Surface Waves for Lab-on-Fiber Optrodes
Michele Scaravilli, Giuseppe Castaldi, Andrea Cusano +1
In this paper, we investigate the possibility to excite Bloch surface waves (BSWs) on the tip of single-mode optical fibers. Within this framework, after exploring an idealized, pr…
Surface sensitivity of Rayleigh anomalies in metallic nanogratings
Silvio Savoia, Armando Ricciardi, Alessio Crescitelli +4
Sensing schemes based on Rayleigh anomalies (RAs) in metal nanogratings exhibit an impressive bulk refractive-index sensitivity determined solely by the grating period. However, th…
Experimental evidence of guided resonances in photonic crystals with aperiodically-ordered supercells
Armando Ricciardi, Marco Pisco, Ilaria Gallina +5
We report on the first experimental evidence of guided resonances (GRs) in photonic crystal slabs based on aperiodically-ordered supercells. Using the Ammann-Beenker (quasiperiodic…
Tuning efficiency and sensitivity of guided resonances in photonic crystals and quasi-crystals: A comparative study
Marco Pisco, Armando Ricciardi, Ilaria Gallina +5
In this paper, we present a comparative study of the tuning efficiency and sensitivity of guided resonances (GRs) in photonic crystal (PC) holed slabs based on periodic and aperiod…
Guided resonances in photonic crystals with point-defected aperiodically-ordered supercells
Ilaria Gallina, Marco Pisco, Armando Ricciardi +4
In this paper, we study the excitation of guided resonances (GRs) in photonic-crystal slabs based on point-defected aperiodically-ordered supercells. With specific reference to per…
Guided resonances in photonic quasicrystals
Armando Ricciardi, Ilaria Gallina, Stefania Campopiano +4
In this paper, we report on the first evidence of guided resonances (GRs) in aperiodically-ordered photonic crystals, tied to the concept of "quasicrystals" in solid-state physics.…
