Active control of anapole states by structuring the phase-change alloy Ge2Sb2Te5
High-index dielectric nanoparticles support a great wealth of multipolar responses but active tunability is still elusive. Here, the authors report how structured Ge2Sb2Te5 can support multipolar Mie resonances and demonstrate the spectral shifting between electric dipole and anapole modes.
