High Quality Factor Metallodielectric Hybrid Plasmonic-Photonic Crystals
A 2D polystyrene colloidal crystal self-assembled on a flat gold surface supports multiple photonic and plasmonic propagating resonance modes. For both classes of modes, the quality factors can exceed 100, higher than the quality factor of surface plasmons (SP) at a polymer–gold interface. The spatial energy distribution of those resonance modes are carefully studied by measuring the optical re...
متن کاملHigh Quality Plasmonic Sensors Based on Fano Resonances Created through Cascading Double Asymmetric Cavities
In this paper, a type of compact nanosensor based on a metal-insulator-metal structure is proposed and investigated through cascading double asymmetric cavities, in which their metal cores shift along different axis directions. The cascaded asymmetric structure exhibits high transmission and sharp Fano resonance peaks via strengthening the mutual coupling of the cavities. The research results s...
متن کاملPlasmonic phase modulator based on novel loss-overcompensated coupling between nanoresonator and waveguide
We present that surface plasmon polariton, side-coupled to a gain-assisted nanoresonator where the absorption is overcompensated, exhibits a prominent phase shift up to π maintaining the flat unity transmission across the whole broad spectra. Bandwidth of this plasmonic phase shift can be controlled by adjusting the distance between the plasmonic waveguide and the nanoresonator. For a moderate ...
متن کاملDouble Fano resonance in a plasmonic double grating structure.
It is shown theoretically and numerically that a simple gratings-based plasmonic structure can support a nearly-degenerate double Fano resonance which can lead to a relatively narrow spectral line shape. The double-resonance spectral location and line-shape are controllable by either adjusting the periodicity and unit-cell of the gratings or by adjusting the angle of incidence of the incoming r...
متن کاملDouble-shell metamaterial coatings for plasmonic cloaking
The ideas of employing the unique properties of meta-materials and plasmonic media for cloaking and invisibility applications have been recently suggested and investigated by several groups [1–5], and they may find numerous applications in physics and technology. While many of the recent designs of the cloaking structures are based on the transformation optics and exact formulas [6], the origin...
