“…Many recent studies are focused on the different approaches to increase the Q-factors of the surface wave resonances and to overcome this limitation. For example, long-range propagating surface plasmon polaritons in thin metal films deposited on the top of a dielectric layer [ 6 , 7 , 8 ], multilayered plasmonic [ 9 , 10 ] structures or photonic crystals [ 11 , 12 , 13 , 14 , 15 ] produce narrow optical resonances and allow for the Q-factor increase. Even more narrow resonances could be produced using all-dielectric structures [ 16 ] instead of plasmonic ones, and utilization of photonic crystals with Tamm surface optical modes.…”

We propose an all-dielectric magneto-photonic crystal with a hybrid magneto-optical response that allows for the simultaneous measurements of the surface and bulk refractive index of the analyzed substance. The approach is based on two different spectral features of the magneto-optical response corresponding to the resonances in p- and s-polarizations of the incident light. Angular spectra of p-polarized light have a step-like behavior near the total internal reflection angle which position is sensitive to the bulk refractive index. S-polarized light excites the TE-polarized optical Tamm surface mode localized in a submicron region near the photonic crystal surface and is sensitive to the refractive index of the near-surface analyte. We propose to measure a hybrid magneto-optical intensity modulation of p-polarized light obtained by switching the magnetic field between the transverse and polar configurations. The transversal component of the external magnetic field is responsible for the magneto-optical resonance near total internal reflection conditions, and the polar component reveals the resonance of the Tamm surface mode. Therefore, both surface- and bulk-associated features are present in the magneto-optical spectra of the p-polarized light.

“…Optical modes arising from the periodicity disturbance at the PC surface are often referred as optical Tamm states [26][27][28]. A crucial property of a PC is that its surface mode is concentrated near the air interface [29][30][31][32], and this is extremely important to form high temperature gradient. Moreover, the long propagation length of surface modes in conjunction with the very high-Q resonance increases the local light intensity by several orders of magnitude [31].…”

“…One possible solution for this problem consists in involving metamaterials, or artificial materials composed of suitably arranged metal-dielectric stacks, which can provide control of surface plasmons for new sensing functionalities [6]. However, the field confinement of these reported metamaterials are relatively weak and exhibit high intrinsic dissipative losses with strong damping of surface plasmons and slow damage by chemical action [7].…”

Graphene supports surface plasmons in the therahertz range, and compared with noblemetal plasmons, they show an extreme level of field confinement and relatively long propagation distances, with the advantage of being highly tunable via electrostatic field.Nevertheless, its interaction with light is normally rather weak. To obtain a more powerful capability of excite plasmons, a combination of graphene and artificial structures (metamaterials) present a powerful tunability for enhancing light-matter interaction.These features make graphene metamaterials a promising candidate for plasmonics and surface plasmon resonance for biological sensors. In this work, we study the plasmon spectra in a finite number of graphene layers on a metallic-dielectric substrate surrounded by materials with different dielectric constants. It is shown that using standard electromagnetic boundary conditions and solving the recurrence relation (a suitable alternative to transfer matrix method) for the coefficients of the electric potential between graphene layers, an explicit effective dielectric function of the metamaterial can be obtained giving the plasmon dispersion relations. It is found that the metal-dielectriclayered graphene structure supports both, high-energy optical plasmons oscillations and out-of-phase low energy acoustic charge density excitations. Experimentally, the Kretschmann configuration can be used to excite the surface plasmon resonances. It is based on the observation of a sharp minimum in the reflection coefficient versus angle (or wavelength) curve.
