Polariton nanophotonics using phase-change materials

Polariton nanophotonics using phase-change materials

Here, the authors experimentally demonstrate a platform for tunable polariton refractive and meta-optics based on hexagonal boron nitride and phase change Ge3Sb2Te6. This combination has the advantage of the long-lived phonon-polariton with switchable refractive index of the phase change material.
