Plasmonic Systems Unveiled by Fano Resonances

ACS Nano, 2012
We show in detail how a derivation of Fano theory can serve as a new paradigm to study, understand, and control the interaction of nano-objects with light. Examples include a plasmonic crystal, a dolmen-type structure sustaining dark and bright plasmon modes, and a nanoshell heptamer.

Fano-resonant graphene metamaterials

Journal of Applied Physics, 2022
The concept of Fano resonance originally discovered in quantum systems has been introduced to the field of optics for the last decade and more. One distinctive feature of the resonance lies in its asymmetric line shape. Graphene metamaterials have attracted much attention for making tunable devices due to the controllable carrier density of graphene ...

Time Resolved Fano Resonances

Physical Review Letters, 2005
Recent advances in the generation of sub-fs extreme ultraviolet pulses and attosecond metrology have opened up the possibility to trace the time evolution of electronic wave packets inside atoms in pump-probe experiments. We investigate the feasibility of observing the buildup of a Fano resonance in the time domain by attosecond streaking techniques. A

Acoustic Fano resonators

2014 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2014
The resonances with asymmetric Fano line-shapes were originally discovered in the context of quantum mechanics (U. Fano, Phys. Rev., 124, 1866–1878, 1961). Quantum Fano resonances were generated from destructive interference of a discrete state with a continuum one.

Fano resonances in kagome fibers

SPIE Proceedings, 2012
Confinement Loss of microstructured fibers whose cladding is composed by a triangular arrangement of tubes of various shapes is theoretically and numerically investigated. Kagome Fibers belong from this family of fibers with cladding tubes with hexagonal shape.

Nonlinear Fano-Resonant Dielectric Metasurfaces

Nano Letters, 2015
Strong nonlinear light-matter interaction is highly sought-after for a variety of applications including lasing and all-optical light modulation. Recently, resonant plasmonic structures have been considered promising candidates for enhancing nonlinear optical processes due to their ability to greatly enhance the optical near-field; however, their small

Silicon slot waveguide Fano resonator

Optics Letters, 2018
The growing interest for Fano resonators during the past decade is due to the narrow line shape observable in their optical spectra. The drastic phase shift occurring at the resonance yields a steep drop from a high to low amplitude. Fano resonances can be obtained by a combination of nanostructures.
