Tunable dynamic Fano resonances in coupled-resonant optical waveguide
, 2015 A route toward lineshape engineering of Fano resonances in photonic structures is theoretically proposed, which uses dynamic modulation of the refractive index of a microcavity. The method is exemplified by considering coupled-resonator optical waveguide

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement
Advanced Materials, EarlyView.The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...

Beyond Conventional Sensing: Hybrid Plasmonic Metasurfaces and Bound States in the Continuum
Nanomaterials, 2023 Fano resonances result from the strong coupling and interference between a broad background state and a narrow, almost discrete state, leading to the emergence of asymmetric scattering spectral profiles.

Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance
Advanced Optical Materials, EarlyView.The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Versatile Control of Spectral Emissivity in Mid‐Infrared Metasurfaces via Silicon Microstructuring
Advanced Optical Materials, EarlyView.A family of metasurfaces is obtained very simply, solely through the structuration of a single‐crystal silicon surface, without any other material involved. Based on the infrared plasmonic behavior of highly doped silicon, further control of surface topography by micro‐ and nano‐structuration is found to enable an avenue of options toward tailoring its

Giant thermopower and figure of merit in single-molecule devices [PDF]
, 2008 We present a study of the thermopower $S$ and the dimensionless figure of merit $ZT$ in molecules sandwiched between gold electrodes. We show that for molecules with side groups, the shape of the transmission coefficient can be dramatically modified by ...

Fano resonances based on multimode and degenerate mode interference in plasmonic resonator system.
Optics Express, 2017 In this paper, three Fano resonances based on three different physical mechanisms are theoretically and numerically investigated in a plasmonic resonator system, comprised of two circular cavities.

Advanced Optical Materials, EarlyView.Quasi‐bound states in the continuum on the Bloch surface wave platform are demonstrated, exhibiting high Q‐factors due to strongly suppressed radiative losses and high sensitivity arising from the large evanescent field inherent to the surface wave. The resonance shows clear shifts after each surface molecular functionalization step, highlighting its ...

Tunable Fano Resonances in Transport through Microwave Billiards
, 2003 We present a tunable microwave scattering device that allows the controlled variation of Fano line shape parameters in transmission through quantum billiards. Transport in this device is nearly fully coherent.
