Fano Resonant Sensing in MIM Waveguide Structures Based on Multiple Circular Split-Ring Resonant Cavities

Micromachines
In this work, a non-through metal–insulator–metal (MIM) waveguide capable of exciting three Fano resonances was designed and numerically studied using the finite element method.

Independently Tunable Ultrasharp Double Fano Resonances in Coupled Plasmonic Resonator System

IEEE Photonics Journal, 2018
A coupled plasmonic resonator system is investigated by both the finite element method (FEM) and the multimode interference coupled-mode theory (MICMT).

Symmetry breaking with coupled Fano resonances

Optics Express, 2008
We describe the effect of symmetry breaking in a system with two coupled Fano resonators. A general criterion is derived and optimal parameter regions for switching are identified. By extending the single resonator behavior we show that one achieves the effect at very low input powers.

Modulation-free laser frequency stabilization via balanced detection of common-path Fano resonance in all-PM fiber cavity

APL Photonics
Laser frequency stabilization is indispensable for extensive applications involving precision measurements, and the best performance has been achieved with the Pound–Drever–Hall technique. However, it relies on a bulky ultrastable Fabry–Pérot cavity with

Ultrasensitive Terahertz Biosensors Based on Fano Resonance of a Graphene/Waveguide Hybrid Structure

Sensors, 2017
Graphene terahertz (THz) surface plasmons provide hope for developing functional devices in the THz frequency. By coupling graphene surface plasmon polaritons (SPPs) and a planar waveguide (PWG) mode, Fano resonances are demonstrated to realize an ...

Manipulating Fano Coupling in an Opto‐Thermoelectric Field

Advanced Science
Fano resonances in photonics arise from the coupling and interference between two resonant modes in structures with broken symmetry. They feature an uneven and narrow and tunable lineshape and are ideally suited for optical spectroscopy.

Widening of the large-angle half-wave wall through a pair of parameter-reversal Fano resonances

Materials & Design
With the high quality (Q) factor, the Fano resonance has only been focused on sensing and switching, while its value in other fields ignored. In this manuscript, according to the Fano spectral characteristics, we have first proposed to use the Fano ...
