Putting piezoelectric sensors into Fano resonances

Microsystems & Nanoengineering
Abstract Piezoelectric resonance sensors are essential to many diverse applications associated with chemical and biological sensing. In general, they rely on continuously detecting the resonant frequency shift of piezoelectric resonators due to analytes accreting on their surfaces in vacuum, gas or fluid.

Fano Resonances in All-Dielectric Oligomers

Nano Letters, 2012
We demonstrate that light scattering by all-dielectric oligomers exhibits well-pronounced Fano resonances with strong suppression of the scattering cross section. Our analysis reveals that this type of the Fano resonance originates from the optically induced magnetic dipole modes of individual high-dielectric nanoparticles.

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.

Experimental realization of tunable Fano resonances in two coupled silicon micromechanical resonators

Physical Review Research
Fano resonances originate from the interaction of a discrete state with a continuum of propagation modes. They have been observed in various quantum and classical systems.

Plasmonic Nanosensors Based on Highly Tunable Multiple Fano Resonances Induced in Metal–Insulator–Metal Waveguide Systems

Nanomaterials
We designed and investigated a plasmonic nanosensor with ultra-high sensitivity and tunability, which is composed of a metal–insulator–metal (MIM) waveguide integrated with a side-coupled resonator (SR) and metal baffle.

Multipolar Analysis in Symmetrical Meta-Atoms Sustaining Fano Resonances

Optics
We present an optical metasurface with symmetrical individual elements sustaining Fano resonances with high Q-factors. This study combines plane-wave illumination and modal analysis to investigate the resonant behavior that results in a suppression of ...
