Abstract

The tunable hybrid polaritons in van der Waals (vdWs) heterostructures present a flexible platform for advanced optical applications, allowing precise control over light-matter interactions. Recently, LiV₂O₅ has emerged as a naturally canalized phonon material characterized by high dielectric permittivity. However, the existing LiV₂O₅-based devices are fixed in their design, which leads to limit the development of actively tunable phonon devices. In this study, we introduce a heterostructure formed by graphene nanoribbons with the LiV₂O₅ structure, resulting in the strong coupling between phonon modes and surface plasmon modes. We explore the potential of electromagnetic hybrid materials to address the limitations of the individual polaritons. Furthermore, we systematically investigate the energy exchange, mode evolution, and coupling strength among three hybridized modes by employing a coupled model with three oscillators, which demonstrates excellent agreement with the simulated results. This work presents a straightforward strategy for infrared applications in thermal management and multi-resonance sensing.

liv2o5 -石墨烯异质结构中的可调谐杂化极化

范德华（vdWs）异质结构中的可调谐杂化极化为先进的光学应用提供了一个灵活的平台，可以精确控制光与物质的相互作用。近年来，LiV2O5作为一种具有高介电常数的天然沟通声子材料出现。然而，现有的基于liv2o5的器件在设计上是固定的，这限制了主动可调谐声子器件的发展。在这项研究中，我们引入了一种由石墨烯纳米带与LiV2O5结构形成的异质结构，导致声子模式和表面等离子体模式之间的强耦合。我们探索电磁杂化材料的潜力，以解决个别极化的限制。在此基础上，采用三振子耦合模型系统地研究了三种杂化模式之间的能量交换、模式演化和耦合强度，结果与仿真结果非常吻合。这项工作为红外在热管理和多共振传感中的应用提供了一个简单的策略。
