Planar refraction and lensing of highly confined polaritons in anisotropic media

Planar refraction and lensing of highly confined polaritons in anisotropic media

Refraction between anisotropic media is still an unexplored phenomenon. Here, the authors investigate the propagation of hyperbolic phonon polaritons traversing α-MoO3 nanoprisms, showing a bending-free refraction effect and sub-diffractional focusing with foci size as small as 1/50 of the light wav...
