Abstract

Photonic funnels, conical waveguiding structures with hyperbolic metamaterial cores, have been proposed – and recently demonstrated at mid-infrared frequencies – as optical links between macro- and nano-scales. All recent realizations of the funnels utilize highly conductive claddings to prevent the leakage of light out of the core. Here we demonstrate that clad-less funnels can significantly outperform their PEC-clad counterparts due to excitation of novel surface modes. We also analyze funnel-light interaction in the time domain and demonstrate temporal separation between diffraction-limited and nano-confined signals. Perspectives of temporal shaping of the nano-confined radiation are also discussed.
