Geometry-symmetry-free and material-symmetry-guaranteed polariton-induced transparency.

ABSTRACT: Plasmon-induced transparency is a classical analogue of electromagnetically induced transparency (EIT). However, its realization and control primarily rely on geometry engineering rather than tuning plasmon polaritons (PPs) themselves, due to their relatively poor tunability. Recently discovered polariton modes in low-symmetry materials exhibit volume-confined field distributions, thickness-dependent dispersions, and in-plane anisotropy, offering possibilities for the realization and manipulation of polariton-induced transparency (PIT). In this study, we theoretically achieve geometry-symmetry-free and material-symmetry-guaranteed PIT based on volume-confined phonon polaritons (vPhPs) in stacked bilayer α-MoO₃ structures. PIT arises from the strong resonance of vPhPs and the sub
