Borophene is one of the few 2D materials that is intrinsically metallic with high carrier densities and strong anisotropy, thus offering the unprecedented potential for new generation optoelectronic devices based on 2D materials. Unfortunately, as an unavoidable consequence of the atomic-scale thickness of borophene that is much smaller than the wavelength of operation, the low absorption of monolayer borophene extremely limits the performance of the borophene-based devices and restricts their relevant applications. It is highly desirable to improve the light absorption of borophene to enhance the light-matter interaction, especially in the commercially important telecommunications waveband. A simple and plausible route is offered by optical Tamm Plasmon Polaritons (TPPs) mode, which is an optical state formed between the metal film and one-dimensional photonic crystal. Besides, TPPs are polarization independent and can be generated without the external compensation of wavevector. In general, TPPs could be excited through direct incidence of electromagnetic waves at normal as well as oblique incidence. To this end, we theoretically present a prototype of nearly perfect absorber in borophene enabled by the Tamm plasmon polaritons mode, which achieved by a novel multilayer photonic configuration consisting of a metal film, a spacer, and one-dimensional photonic crystal, and investigated the enhancement of light absorption of monolayer borophene which is positioned within the spacer layer. The monolayer borophene position is optimized based on the nature of field localization in the photonic crystal region. Benefiting from the strong interaction of borophene with the confined field at metal-dielectric interface generating by the Tamm plasmon polaritons mode, the absorption can be enhanced up to 95.53% and 96.62% at the wavelength of 1 550 nm and 1 607 nm along x-direction and y-direction respectively. Then, the transfer-matrix method, an effective approach for the theoretical calculations of light propagation characteristics in the multilayer photonic configurations, is employed to achieve the spectral response in the multilayer structures. The simulated results agree well with the analytical calculations. The proposed absorber shows achieved nearly perfect light absorption is an order of magnitude in optical absorption higher than that of free-standing monolayer borophene, which contributes to the significant enhancement of light-matter interaction. It is also found that the operating resonant wavelength and height of sharp absorption peak could be effectively adjusted by altering the electron density of borophene, the period numbers of dielectric grating and the position of borophene in the resonator. The maximum absorption increases accompanying with the wavelength shift of the corresponding absorption peak when the electron density increases increasingly. The enhancement of the absorption is caused by the increasing imaginary part of the effective permittivity and the slight blueshift of the peak wavelength is caused by the real part of the effective permittivity. Meanwhile, we find that the thicknesses of Si₃N₄ and SiO₂ layers in the one-dimensional photonic crystal also play crucial role in the absorption for the borophene layer. The absorption peak possesses a nearly linear redshift with an increasing of the Si₃N₄ thickness and SiO₂ thickness. In addition, we investigate the dependence of the light absorption in monolayer borophene on the light incident angle. The maximum absorption can be dynamically tuned by adjusting the incident angle and the wavelength of the absorption peak exhibits a blueshift with the increase of the incident angle. These results can offer a promising way for the tunability and selectivity of the enhancement of light-matter interaction in 2D materials. The proposed infrared borophene absorber based on Tamm plasmon polaritons exhibits excellent performance including flexible tunability and high absorption, which is expected to be utilized in a wide range of potential applications in optical communication, photodetection and imaging system.
