Abstract

Calcite is a birefringent material with optical anisotropy that becomes extreme in the infrared, allowing for the excitation of highly-directional, sub-diffractional hyperbolic modes. In this talk, I will discuss our recent work that focuses on understanding the optical behavior of hyperbolic modes supported within asymmetric nanostructures formed in calcite crystals with in-plane anisotropy, including our recent findings that demonstrate how the resonant frequency and directional power flow can be tuned by simply rotating gratings with respect to the crystal axes of calcite – without changing the shape of the gratings.
