Abstract
Photonic funnels, conical structures with hyperbolic cores, that have been recently demonstrated at mid-IR frequencies, provide a platform to avoid the diffraction limit and enable a smooth optical link between the nanoscale and microscale. Orbital angular momentum (OAM) of beams play important role in optical manipulation, microscopy, and potentially optical communications.. In this work we analyze theoretically the interaction structured light (light that has non-zero OAM) with photonic funnels. In particular, we study the effect of light confinement, facilitated through the geometric profile of the funnel, on spatial structure of the mode, and its local intensity.
