Hybridized surface lattice modes in intercalated 3-disk plasmonic crystals for high figure-of-merit plasmonic sensing

Abstract

Engineering the spectral lineshape of plasmonic modes by various electromagnetic couplings and mode interferences enables significant improvements for plasmonic sensing. However, bulk and surface sensitivities remain constrained by a trade-off...

Nanostructured plasmonic chips employing nanopillar and nanoring hole arrays for enhanced sensitivity of SPR-based biosensing

“…2 that the plasmon resonance dips are deeper in diamond nanopillar and diamond nanoring hole arrays than cylindrical nanopillar and cylindrical nanoring hole arrays. Although, the diamond nanopillar arrays display a smaller shi (smaller S S ) in plasmon resonance wavelength $2.1 a $0.14 a Nanodisk array 40 $1.38 a $0.016 a Nanohole array 52 $2.5 a $0.33 a Fiber nanoprobe 53 $0.41 a $0.0028 a Gold-coated silver nanoprism 54 $6.67 a $0.046 a 3-Disk array 55 6.06 -2D plasmonic crystals 56 $1.67 a -Nanogratings 57 $0.71 a -Ring resonator arrays 58 $1.6 $0.19 Non-uniform nanogratings 43 than the cylindrical nanopillar arrays. The shi in the plasmon resonance dips depends upon the high E-eld values in the biolayer region.…”

Dynamic matrix theory for resonance response of plasmonic metamaterial lattice

“…Therefore, it is clear that the magnetic and electric energy can be respectively regarded as generalized kinetic and elastic potential energy, while the dipole energy in the external field should be regarded as generalized gravitational potential energy. The Lagrange model about the resonance of two-body systems has been investigated in previous studies [21,22,30]. While for a many-body system discussed here, it is more suitable to begin with a matrix form.…”

“…A direct way to enhance resonance is to place many units together to construct an oligomer or lattice. The near field coupling among these units will cause mode hybridization, and the corresponding LSP resonance is much more complicated than the case of isolated ones [19][20][21][22][23][24]. Recent studies also show that lattice with asymmetric dimer cell or oligomer structure can exhibit stronger resonance than that of symmetric ones [25][26][27][28][29].…”

Plasmonic Nanostructure Engineering with Shadow Growth

“…[154,259,260] The sharp (high Q-factor) resonance can be achieved when individual plasmonic nanoparticles are identical (i.e., same geometry and material composition) and arranged with a regular distance near λ*. [261] It has been utilized for selective light filtering, [262] LSPR sensing to reduce the FWHM (so high FOM), [263,264] and recently, the photonic lasing effect. [61,265,266] Furthermore, this SLR still occurs under a chiral influence so gives rise to unique chiroptical lattice resonance, if the nanoparticles are chiral, for example, crescents (Figure 4i).…”
