Hyperbolic optics and superlensing in room-temperature KTN from self-induced k-space topological transitions

Broadband hyperbolic mediums are essential building blocks for several photonic applications. Here the authors show how nonlinearity, based on a giant electro-optic response, transforms a bulk KTN perovskite into a 3D hyperbolic material
