The enhancement of the Goos–Hänchen (GH) shift has become a research hotspot due to its promoted application of the GH effect in various fields. However, currently, the maximum GH shift is located at the reflectance dip, making it difficult to detect GH shift signals in practical applications. This paper proposes a new metasurface to achieve reflection-type bound states in the continuum (BIC). The GH shift can be significantly enhanced by the quasi-BIC with a high quality factor. The maximum GH shift can reach more than 400 times the resonant wavelength, and the maximum GH shift is located exactly at the reflection peak with unity reflectance, which can be applied to detect the GH shift signal. Finally, the metasurface is used to detect the variation in the refractive index, and the sensitivity can reach 3.58 × 106 μm/RIU (refractive index unit) according to the simulation’s calculations. The findings provide a theoretical basis to prepare a metasurface with high refractive index sensitivity, a large GH shift, and high reflection.

This study revisits an optomechanical cavity system to investigate how the Casimir force affects the manipulation of a diffraction grating. The proposed model consists of two mirrors, one of which is fixed while the other vibrates, and an external plate is used to generate the Casimir effect through the vibrating mirror. The Casimir effect has the potential to modify the properties of the output probe field (OPF), resulting in the phenomenon known as optomechanically induced transparency (OMIT), as reported in a previous study (Sci. Rep. 6, 27102 (2016)). Interestingly, we observed that, when the Casimir effect exist, the maximum energy is transported to higher order. This theoretical realization of the diffraction grating could be feasibly tested in a physical experiment.
