Negative refraction in hyperbolic hetero-bicrystals

ORAL

Abstract

Select quantum materials can support polaritons, hybrid light matter waves, with sub-diffraction-limited confinement. In this talk, I will overview recent progress on polaritons in hyperbolic materials, which propagate as conical rays throughout the bulk of these crystals. I will discuss polaritons in a class of hyperbolic hetero-bicrystals. Our data reveals negative refraction, spectral gaps and wave localization in these systems [1].
