Non-dispersive Fano resonances in hybrid plasmonic-distributed Bragg reflector structures

چکیده
Abstract Fano resonance due to coupling of plasmon mode and Bragg modes is revealed without strong angular dependence based on Au nanoparticle distributed reflectors (Au NPoDBRs). This interference involves three-modes-coupling: the nanoparticle’s resonance, dispersive modes, non-dispersive modes. It can be interpreted as a consequence two processes: plasmonic between broad mode, narrowed mode. shows little incidence angle but high tunability with top-layer thickness, which exploitable for novel nanophotonic devices dispersion engineering.

Fano resonances in nanoscale structures
Modern nanotechnology allows one to scale down various important devices sensors, chips, fibers, etc. and thus opens up new horizons for their applications. The efficiency of most of them is based on fundamental physical phenomena, such as transport of wave excitations and resonances. Short propagation distances make phase-coherent processes of waves important. Often the scattering of waves inv...
متن کاملMechanisms of Fano resonances in coupled plasmonic systems.
Fano resonances in hybridized systems formed from the interaction of bright modes only are reported. Despite precedent works, we demonstrate theoretically and experimentally that Fano resonances can be obtained by destructive interference between two bright dipolar modes out of phase. A simple oscillator model is provided to predict and fit the far-field scattering. The predictions are verified...
متن کاملGraphene-based tunable plasmonic Bragg reflector with a broad bandwidth.
We propose and numerically analyze a plasmonic Bragg reflector formed in a graphene waveguide. The results show that the graphene plasmonic Bragg reflector can produce a broadband stopband that can be tuned over a wide wavelength range by a small change in the Fermi energy level of graphene. By introducing a defect into the Bragg reflector, we can achieve a Fabry-Perot-like microcavity with a q...

In nowadays intergrated circuit design, the diffraction limit has restricted the downscaling of the conventional electronic components. Surface Plasmon Polaritons (SPPs) are quantized charge density oscillations that occur at the interface between metal and dielectric materials when photons couple to the free electron gas of the metal. The extraordinary properties of SPPs can be utilized for su...
متن کاملAugmenting second harmonic generation using Fano resonances in plasmonic systems.
Significant augmentation of second harmonic generation using Fano resonances in plasmonic heptamers made of silver is theoretically and experimentally demonstrated. The geometry is engineered to simultaneously produce a Fano resonance at the fundamental wavelength, resulting in a strong localization of the fundamental field close to the system, and a higher order scattering peak at the second h...
