“…The spectral position of this peak, in fact, is mainly dictated by the value of the lattice period and marginally by the geometric dimensions of the dimers. Similar effects have been already noticed in periodic arrays of plasmonic antennas 15 and in arrays of dielectric nanowires 14 . Nevertheless, according to our knowledge, this is the first attempt to combine the SLR with the local resonances of dielectric dimers to tailor an engineered substrate for SERS application.…”

In this paper, we propose the use of high refractive index dimers for the realization of a surface enhanced Raman spectroscopy substrate, with an average enhancement factor comparable to plasmonic structures. The use of low loss dielectric materials is favorable to metallic ones, because of their lower light absorption and consequently a much lower heating effect of the substrate. We combined two different mechanisms of field enhancement to overcome the main weakness of dielectric dimers: a low enhancement factor compared to the plasmonic ones. A first mechanisms is associated to surface lattice resonances. This generates a narrow-band high enhancement, which is exploited to enhance the excitation light. A second mechanism exploits the local field enhancement between the dimers’ resonators, for the band where the molecule Raman emission spectrum is located. The fact that both field enhancements can be tuned by acting on separate geometric parameters, makes possible to optimize the design for many different molecules. The optimized structure and its performance is presented together with a discussion of the different enhancement mechanisms.

“…However, the EF of a single dielectric dimer has been shown to reach levels consistently below the levels of plasmonic scatterers. Dimers placed in a periodic array were already studied and it has been shown that Surface Lattice Resonances (SLR) are present 14,15 . These resonances are narrow band and Fano line shaped.…”

“…Strong coupling between lattice modes in arrays of nanoparticles (NPs) and Mie-type oscillations localized within a single NP, has attracted significant attention over the last decade. Pioneering theoretical predictions for 1D arrays of Ag NPs [1-3] and consequent experimental verification for 2D arrays of Au NPs [4][5][6] have given a momentum to a great number of excellent applications of collective lattice resonances in lasers [7][8][9][10][11][12], biosensors [13][14][15][16][17][18], emission enhancement [19][20][21][22], and color printing [23][24][25][26].…”

Collective lattice resonances in disordered and quasi-random all-dielectric metasurfaces

et al. 2019

Collective lattice resonances in disordered 2D arrays of spherical Si nanoparticles (NPs) have been thoroughly studied within the framework of the coupled dipole approximation. Three types of defects have been analyzed: positional disorder, size disorder, and quasi-random disorder. We show that the positional disorder strongly suppresses either the electric dipole (ED) or the magnetic dipole (MD) coupling depending on the axis along which the NPs are shifted. Contrary, size disorder strongly affects only the MD response, while the the ED resonance can be almost intact, depending on the lattice configuration. Finally, random removing of NPs from an ordered 2D lattice reveals a quite surprising result: hybridization of the ED and MD resonances with lattice modes remains observable even in the case of random removing of up to 84% of the NPs from the ordered array. Reported results could be important for rational design and utilization of metasurfaces, solar cells and other all-dielectric photonic devices.

“…[171] Condensed phase MVCD for a long time resisted thorough quantum chemical analysis, and available models explained it only qualitatively. [12,172,173] This changed in 2018 when MVCD intensities could be reproduced using common quantumchemical software (Figure 7). [13] The MVCD theory, similarly as for (electronic) MCD is based on the transition electric dipole moments perturbed by the magnetic field.…”

Recent Trends in Chiroptical Spectroscopy: Theory and Applications of Vibrational Circular Dichroism and Raman Optical Activity

Chiroptical spectroscopy exploring the interaction of matter with polarized light provides many tools for molecular structure and interaction studies. Here, some recent discoveries are reviewed, primarily in the field of vibrational optical activity. Technological advances results in the development of more sensitive vibrational circular dichroism (VCD), Raman optical activity (ROA) or circular polarized luminescence (CPL) spectrometers. Significant contributions to the field also come from the light scattering and electronic structure theories, and their implementation in computer systems. Finally, new chiroptical phenomena have been observed, such as enhanced circular dichroism of biopolymers (protein fibrils, nucleic acids), plasmonic and resonance chirality‐transfer ROA experiments. Some of them are not yet understood or attributed to instrumental artifacts so far. Nevertheless, these unknown territories also indicate the vast potential of the chiroptical spectroscopy, and their investigation is even more challenging.
