论文摘要
自然双轴双曲材料Moo $ _3 $中的各向异性双曲音声子偏振子(PHP)为中红外的纳米光子学开辟了新的途径,而积极的可调性为$α$ -MOO-moo $ _3 $ _3 $ phps仍然是一个紧迫的问题。相变材料VO $ _2 $和石墨烯。据观察,$α$ -MOO $ _3 $ phps大大取决于PHP的传播平面角。 VO $ _2 $的金属到疑虑器相过渡对$α$ -MOO $ _3 $ _3 $/vo $ _2 $结构的杂交phps具有重大影响,并允许获得主动调谐$α$ -MOO $ _3 $ _3 $ phps,这在传播平面pHP的角度时尤其明显。
Anisotropic hyperbolic phonon polaritons (PhPs) in natural biaxial hyperbolic material MoO$_3$ has opened up new avenues for mid-infrared nanophotonics, while active tunability of $α$-MoO$_3$ PhPs is still an urgent problem needing to be solved.In this study, we present a theoretical demonstration of actively tuning $α$-MoO$_3$ PhPs using phase change material VO$_2$ and graphene. It is observed that $α$-MoO$_3$ PhPs are greatly depending on the propagation plane angle of PhPs. The metal-to-insulator phase transition of VO$_2$ has a significant effect on the hybridization PhPs of the $α$-MoO$_3$/VO$_2$ structure and allows to obtain an actively tunable $α$-MoO$_3$ PhPs, which is especially obvious when the propagation plane angle of PhPs is 90.
