## Description

- description: Polaritons in van-der-Waals materials (vdWMs) promise high confinement
    and multiple tailoring options by resonators and launching structures which conventionally
    require cumbersome lithography techniques. Optical programming of phase-change
    materials (PCMs) offers fast and reconfigurable fabrication of these structures.
    As the plasmonic PCM In3SbTe2 can be switched between a dielectric and metallic
    phase, In3SbTe2 is promising for optical programming of metallic launching structures
    to tailor and confine polaritons in vdWMs. Here, we combine the vdWM hexagonal
    boron nitride (hBN) with In3SbTe2 and optically program circular resonators for
    hBN’s phonon polaritons into In3SbTe2. We investigate the polariton resonators
    with near-field optical microscopy. Demonstrating the reconfigurability, we decrease
    the resonator diameter to increase the confinement up to λ/39 and achieve a quality
    factor of 72. Finally, we fabricate a focusing structure for hBN’s polaritons
    whose focal point we reconfigure. We promote In3SbTe2 as a versatile platform
    for rapid prototyping of polariton optics in vdWMs.
