Abstract

In this paper, we proposed a layered structure composed of two kinds of materials. The interface of this structure has zero-refractive-index (ZRI) frequencies in near-infrared regime at which the relative dielectric constant or permeability is zero. We analyze the dispersion relation of various materials, design a layered structure, and explore the possibility of realizing ZRI by using metal and two-dimensional materials. The results show that at the interface between borophene and chromium film (BP-Cr) there are ZRI points in a large range from visible to near-infrared. On this basis, the third-order nonlinear effects of two-layer structure based on BP-Cr are examined. The particularity of the ZRI-frequency point of the structure meets phase matching very well, which greatly enhances the intensity of the third-harmonic generation. It is also 10–100 times that of silicon under the same conditions, indicating that Bp-Cr combination will have a potential application prospect in nonlinear optical field. [ABSTRACT FROM AUTHOR]
