Quantitatively Exploring Giant Optical Anisotropy of Quasi-One-Dimensional Ta₂NiS₅.

ABSTRACT: Optical anisotropy offers a heightened degree of flexibility in shaping optical properties and designing cutting-edge devices. Quasi-one-dimensional Ta₂NiS₅, with giant optical anisotropy, has been used in the development of new lasers and sensors. In this research endeavor, we successfully acquired the complete dielectric tensor of Ta₂NiS_5, utilizing the advanced technique of Mueller matrix spectroscopic ellipsometry, enabling a rigorous quantitative assessment of its optical anisotropy. The results indicate that Ta₂NiS₅ demonstrates giant birefringence and dichroism, with Δn_max = 1.54 and Δk_max = 1.80. This pursuit also delves into the fundamental underpinnings of this optical anisotropy
