Abstract
Anisotropic hyperbolic phonon polaritons (PhPs) in natural biaxial hyperbolic material MoO has opened up new avenues for mid-infrared nanophotonics, while active tunability of -MoO PhPs is still an urgent problem needing to be solved.In this study, we present a theoretical demonstration of actively tuning -MoO PhPs using phase change material VO and graphene. It is observed that -MoO PhPs are greatly depending on the propagation plane angle of PhPs. The metal-to-insulator phase transition of VO has a significant effect on the hybridization PhPs of the -MoO/VO structure and allows to obtain an actively tunable -MoO PhPs, which is especially obvious when the propagation plane angle of PhPs is 90.
