Phase protection of Fano-Feshbach resonances [PDF]

open access: yesNature Communications, 2020
AbstractDecay of bound states due to coupling with free particle states is a general phenomenon occurring at energy scales from MeV in nuclear physics to peV in ultracold atomic gases. Such a coupling gives rise to Fano-Feshbach resonances (FFR) that have become key to understanding and controlling interactions—in ultracold atomic gases, but also ...

High-Performance Nano-Sensing and Slow-Light Applications Based on Tunable Multiple Fano Resonances and EIT-Like Effects in Coupled Plasmonic Resonator System

open access: yesIEEE Access, 2020
A basic plasmonic system, consisting of a stub metal-insulator-metal (MIM) waveguide coupled with a ring resonator, is presented to realize Fano resonance and electromagnetically induced transparency-like (EIT-like) effect, which are numerically ...

Fano resonances from gradient-index metamaterials [PDF]

open access: yesScientific Reports, 2016
AbstractFano resonances – resonant scattering features with a characteristic asymmetric profile – have generated much interest, due to their extensive and valuable applications in chemical or biological sensors, new types of optical switches, lasers and nonlinear optics.

Optical vortices at Fano resonances

open access: yesOptics Letters, 2012
We study the transmission properties of a one-dimensional array with intersite side-coupled defect and demonstrate that, as the system undergoes sharp Fano resonance, it exhibits geometry-induced vorticity of the energy flux. The optical vortex inverts its handedness at the Fano resonance, revealing a strong link between two phenomena, both being of ...

Fano-Like Resonance in an All-in-Fiber Structure

open access: yesIEEE Photonics Journal, 2019
We achieve Fano-like resonances in an all-in-fiber structure embedded with an in-line Mach-Zehnder interferometer (MZI). A fiber Bragg grating is inserted into MZI's one arm to form a resonance, which functions as the discrete state of the Fano ...

Magnetically Controlled Atomic–Plasmonic Fano Resonances [PDF]

open access: yesNano Letters, 2017
Following the efforts of size reduction and the integration of light and vapor systems, great promise is held in the integration of vapor and confined electromagnetic waves. By confining light to nanoscale dimensions, fundamental properties of light-vapor interactions may vary significantly.

Fano resonances in plasmonic core-shell particles and the Purcell effect

open access: yes, 2018
Despite a long history, light scattering by particles with size comparable with the light wavelength still unveils surprising optical phenomena, and many of them are related to the Fano effect.

Glycerol concentration sensor based on the MIM waveguide structure

open access: yesFrontiers in Physics, 2022
Glycerol is widely used in medicine, industry and skin care products. This study investigated a high-sensitivity glycerol concentration sensor based on double Fano resonances in a metal-insulator-metal (MIM) waveguide structure, established a coupling ...

Control of quantum interference in molecular junctions: Understanding the origin of Fano and anti- resonances

open access: yes, 2013
We investigate within a coarse-grained model the conditions leading to the appearance of Fano resonances or anti-resonances in the conductance spectrum of a generic molecular junction with a side group (T-junction).

Electron transport in a two-terminal Aharonov-Bohm ring with impurities

open access: yes, 2009
Electron transport in a two-terminal Aharonov-Bohm ring with a few short-range scatterers is investigated. An analytical expression for the conductance as a function of the electron Fermi energy and magnetic flux is obtained using the zero-range ...
