“…Fortunately, due to its high carrier concentration, the emerging 2D material borophene can support the plasmonic response in the optical communication band [21]. It has been found that the gate voltage can be used to tune the carrier concentration of borophene [22][23][24]. In addition, in order to stabilize borophene, some effective methods can be applied, such as hydrogenation, solvation and substrate-assisted [25].…”

Polarized light has a number of potential applications in the communication bands, including optical communication, polarization imaging, quantum emission, and quantum communication. Nonetheless, there is a need to enhance the dynamic tunability, broadband operation, and flexibility of polarization control. Here, a borophene structure is proposed to dynamically control the polarization state of reflected light. The coherent excitation of localized surface plasmons (LSPs) empowers the achievement of a perfect linearly-circularly polarization conversion at the commercially important communication wavelength of 1550 nm. The dynamic tunability and switching, as well as the arbitrary polarization conversion, are enabled over a wide spectral range by modulating the carrier concentration of borophene. Moreover, by deforming the borophene array and alternately stimulating the upper and lower layers of the LSPs mode, the polarization rotation direction can be flexibly switched. Finally, the process of near-field coupling between the LSPs and dipole light source positioned at a chosen hotspot is demonstrated. This coupling enables polarization-tunable spontaneous emission enhancement, with a spontaneous emission enhancement exceeding 900. The proposed design contributes to enhancing the speed and efficiency of communication within the domain of quantum communication.

“…18,[28][29][30][31][32] Graphene in particular has gained much attention due to its high conductivity and its atomic sharpness which result in extremely large, localised field gradients being generated at its edges. 18,33 Indeed, graphenebased devices have been used to capture and integrate various nanomaterials. 17,34,35 In addition, graphene has many appealing qualities as an electrode material such as a gate-tunable carrier concentration, optical transparency, plasmonic activity, 36 and long spin-diffusion lengths, 37 which make it attractive for applications such as biosensing 38 and spintronics.…”
