Abstract

In this paper, we demonstrate a vanadium dioxide (VO₂) integrated chiral metamaterial exhibiting tunable chiroptical responses at terahertz frequencies. Simulated results show that a circular dichroism of ~40° and a maximum polarization rotation of ~200°/λ can be achieved around 0.7 THz with VO₂ in its metallic phase. More importantly, the chiroptical response from the hybrid metamaterial varies dramatically with the phase transition determined by the THz conductivity of VO₂. Our results reveal that the unification of structured metals and phase-change materials provides the foundation to establish a new paradigm for THz chiroptical metadevices.
