“…As a result, at an ordinary dielectric interface, the GH shift will be the same as the incident wavelength. The development of weak measurement technology has expanded the GH shift's potential applications, [4] including the accurate measurement of optical properties. [5] Several studies have been conducted on various dielectric surfaces to enhance the GH shift, such as the metasurfaces, [6] topological insulators, [7] Weyl semimetals, [8] and metamaterials (MMs), [9,10] as well as two-dimensional (2D) atomic crystals, [11] and so on.…”

We conduct a theoretical analysis of the massive and tunable Goos-Hänchen (GH) shift on a polar crystal covered with periodical black phosphorus (BP)-patches in the THz range. The surface plasmon phonon polaritons (SPPPs), which are coupled by the surface phonon polaritons (SPhPs) and surface plasmon polaritons (SPPs), can greatly increase GH shifts. Based on the in-plane anisotropy of BP, two typical metasurfaces models are designed and investigated. The enormous GH shift about -7565.58 λ0 is achieved by adjusting the physical parameters of BP-patches. In the designed metasurface structure, the maximum sensitivity accompanying large GH shifts can reach about 6.43 × 108 λ 0/RIU, which is extremely sensitive to the size, carrier density, and layer number of BP. Compared with a traditional surface plasmon resonance sensor, the sensitivity is increased at least two orders of magnitude. We believe that investigating metasurface-based SPPPs sensors could lead to high-sensitivity biochemical detection applications.

“…Relying on its unique temperature-dependent properties, BK7 glass has also been proposed to combine monolayer graphene to explore the GH shifts in multilayered structures. For example, Zhou et al discuss the GH shift in the structure of monolayer graphene-BK7 glass substrate and found that its GH value increases nearly linearly as the temperature because of the temperature-controlled refractive index of the BK7 glass substrate [36]. Besides, Zhou et al theoretically investigated the GH shift of the BK7 glass slab sandwiched by two monolayer graphenes.…”

BK7 glass has an unusual temperature-dependent refractive index and thickness, which provides a promising platform for uncovering the temperature-related optical phenomena and applications. Here, we theoretically demonstrate that monolayer graphene based BK7 glass grating structure has two Goos-Hänchen (GH) peaks with respective magnitudes of 2564λ and 1993λ, and their corresponding reflectances are also high. The electromagnetic field distribution in this structure directly reveals that the enhanced GH shifts can be ascribed to the excitation of the guide mode resonances in the waveguide dielectric layer below BK7 glass grating structure and their high reflectances are granted by the constructive interferences between the reflected waves. In addition, the magnitudes of the GH peaks can be controlled by the temperature of BK7 glass as well as the chemical potential of monolayer graphene. We also evaluate the temperature sensing property of this structure based on the GH shifts and find that its maximum temperature sensitivity can be up to 50017 μm/°C . The enhanced and controlled GH shift presented in monolayer graphene based BK7 glass grating structure shows promise for the applications, such as, optical sensors, temperature sensors, and optoelectronic detectors.

“…There-into, Brunner et al [10] proposed that the WVA scheme using the imaginary weak value amplification can result in 3 orders of magnitude higher precision than the traditional interference method. Therefore, the WVA scheme based on the imaginary weak value is currently used in the field of biosensors, such as a new chiral sensor based on weak measurement for estimation of a trace amount of chiral molecule [34], a tunable and high-sensitivity temperature-sensing method via WVA of Goos-änchen (GH) shifts in a graphene-coated system [35], even an optical system based on optical rotation via weak measurement for detection of single-and double-strand state of DNA [36]. Furthermore, there have been several optimization schemes to improve the WVA scheme based on analysis of its Fisher information [23,32,37,38].…”
