Abstract
Metallic and dielectric domains in phase change materials (PCM) provide spatially localized changes in the local dielectric environment, enabling launching, reflection, and transmission of hyperbolic polaritons (HPs) at the PCM domain boundaries, and tuning the wavelength of HPs propagating in hyperbolic materials over these domains, providing a methodology for realizing planar, sub-diffractive refractive optics. This approach offers reconfigurable control of in-plane HP propagation to provide design optical functionality because the phase change material can be manipulated by changing the local structure, for example, to manipulate polaritons in the adjacent hyperbolic material, thus tuning the wave propagation properties of the polaritons in the hyperbolic material.
