Abstract

In this work we report broadband refraction and diffraction experiments in a ferroelectric perovskite, a solid-solution K_0.997Ta_0.64Nb₀.36:Li_0.003 (KTN:Li), that demonstrate an index of refraction of n > 26 across the entire visible spectrum. The sample has a natural-occurring room temperature phase that propagates visible light along its normal axis without significant diffraction or chromatic dispersion, irrespective of beam size, intensity, and angle of incidence.
