“…When the angular interrogation [ 4 , 5 , 6 ] with a monochromatic beam is considered, a sharp minimum (dip) is resolved in the angular spectrum. Similarly, when the wavelength interrogation [ 19 , 20 , 21 , 22 , 26 ] with a white-light source is considered, a dip is resolved in the reflection spectrum. In addition, a large number of fiber optic sensors utilizing the SPR have been proposed and realized as those presented in review papers [ 27 , 28 , 29 , 30 ] or in [ 31 , 32 ].…”

We report on a highly sensitive measurement of the relative humidity (RH) of moist air using both the surface plasmon resonance (SPR) and Bloch surface wave resonance (BSWR). Both resonances are resolved in the Kretschmann configuration when the wavelength interrogation method is utilized. The SPR is revealed for a multilayer plasmonic structure of SF10/Cr/Au, while the BSWR is resolved for a multilayer dielectric structure (MDS) comprising four bilayers of TiO2/SiO2 with a rough termination layer of TiO2. The SPR effect is manifested by a dip in the reflectance of a p-polarized wave, and a shift of the dip with the change in the RH, or equivalently with the change in the refractive index of moist air is revealed, giving a sensitivity in a range of 0.042–0.072 nm/%RH. The BSWR effect is manifested by a dip in the reflectance of the spectral interference of s- and p-polarized waves, which represents an effective approach in resolving the resonance with maximum depth. For the MDS under study, the BSWRs were resolved within two band gaps, and for moist air we obtained sensitivities of 0.021–0.038 nm/%RH and 0.046–0.065 nm/%RH, respectively. We also revealed that the SPR based RH measurement is with the figure of merit (FOM) up to 4.7 × 10−4 %RH−1, while BSWR based measurements have FOMs as high as 3.0 × 10−3 %RH−1 and 1.1 × 10−3 %RH−1, respectively. The obtained spectral interferometry based results demonstrate that the BSWR based sensor employing the available MDS has a similar sensitivity as the SPR based sensor, but outperforms it in the FOM. BSW based sensors employing dielectrics thus represent an effective alternative with a number of advantages, including better mechanical and chemical stability than metal films used in SPR sensing.

“…The GH shift of p-polarized laser beam reflected from ITO surface under complex field has been studied [23]. In addition, two-dimensional (2D) nanomaterial with high thermal conductivity, carrier mobility, wide band optical response spectrum and strong nonlinear optical properties have attracted more and more attention [24,25]. The 2D materials include graphene [26,27], black phosphorus (BP) [28,29], and transition metal dichalcogenides (TMDCs) [30,31].…”

Surface plasmon resonance (SPR) with two-dimensional (2D) materials is proposed to enhance the sensitivity of sensors. A novel Goos–Hänchen (GH) shift sensing scheme based on blue phosphorene (BlueP)/transition metal dichalogenides (TMDCs) and graphene structure is proposed. The significantly enhanced GH shift is obtained by optimizing the layers of BlueP/TMDCs and graphene. The maximum GH shift of the hybrid structure of Ag-Indium tin oxide (ITO)-BlueP/WS2–graphene is −2361λ with BlueP/WS2 four layers and a graphene monolayer. Furthermore, the GH shift can be positive or negative depending on the layer number of BlueP/TMDCs and graphene. For sensing performance, the highest sensitivity of 2.767 × 107λ/RIU is realized, which is 5152.7 times higher than the traditional Ag-SPR structure, 2470.5 times of Ag-ITO, 2159.2 times of Ag-ITO-BlueP/WS2, and 688.9 times of Ag-ITO–graphene. Therefore, such configuration with GH shift can be used in various chemical, biomedical and optical sensing fields.

“…Сенсоры на основе эффекта нарушенного полного внутреннего отражения применяются для измерения коэффициента преломления газов, жидкостей, в частности, в биологических приложениях [1,2], поэтому их исследование активно ведется в настоящее время. Вариантами реализации таких сенсоров являются разные оптические схемы, в частности схема Кречмана на основе призмы, или иные схемы на основе дифракционной структуры, в которых в качестве сигнального репера используется узкий спектральный минимум интенсивности в отражении, который в литературе имеет устоявшееся название поверхностного плазмонного резонанса (ППР, surface plasmon resonance, SPR) и который является результатом максимизации поглощения света в сенсорной структуре [3,4]. В настоящей работе исследованы свойства одного из новых вариантов сенсоров, использующих эффект полного внутреннего отражения и поверхностного плазмонного резонанса в конфигурации Кречмана.…”

The analytical formulas, describing spectral properties of sensor based on oblique incidence reflection interferometer in Kretschmann optical scheme. The sensor is designed for measuring the refractive index of analyte (liquid or gas) exploiting the effect of total internal reflection in multilayered metal-dielectric structure. The properties of comprised in the structure thin metal layer, that are necessary for optimization of sensor’s spectral profile, are defined. The spectral profile represents peaks with varying width. The oblique quaterwave dielectric layers are also used in the structure. The analytical properties of sensor depending on light polarization are given: resolution, sensitivity, contrast and figure of merit (FOM). It is shown in the paper, that sensor shows high grade parameters in both polarizations, but it is preferably to use S polarization to maximize FOM due to higher finesse in the sensor structure. The method of fabrication of such sensor structure with optical control during vacuum sputtering is proposed.
