Metal-free low-loss negative refraction in the mid-infrared region

X. L. Liu and Z. M. Zhang

Low-loss all-angle negative refraction is predicted in the mid-infrared region based on doped-silicon nanowire arrays. Loss-enhanced transmission and absence of resonances account for the broadband high figure of merit (FOM), which could be an order of magnitude greater than those reported previou ... [Appl. Phys.
