Abstract

Waveguides with extremely anisotropic metamaterial cores support propagating modes even when their cross section is deeply subwavelength. A funnel-shaped structure with microscale base, nanoscale tip, and hyperbolic core can therefore act as an efficient optical link between the diffraction-limited and subwavelength domains. In this work we analyze the potential applications of this platform for mid-IR near-field scanning optical microscopy. We present the relationship between the shape and composition of the funnels and the resulting compression of light, characterized by both the intensity and the spread of electromagnetic field in the vicinity of the funnel tip.
