Van der Waals (vdW) materials are at the core of modern optoelectronics and nanophotonics. However, relatively limited research attention is devoted to their giant optical anisotropy. Here, we demonstrate that the use of giant anisotropy leads to the next-generation integrated circuits and optical elements, determining the exact values of anisotropic dielectric permittivity tensor for the variety of vdW materials in the broad spectral range (250–1700 nm) using cross-validation of far- and near-field techniques, accompanied by first-principle calculations. Our results show high refractive index, transparency over the whole studied spectral range and giant optical anisotropy for all investigated vdW materials. Furthermore, we suggest applications of vdW materials for chiral optics and integrated photonics.
This work is dedicated to laser engineering of spherical resonant Mie-excitonic nanoparticles from layered materials, particularly Transition Metal Dichalcogenides (TMDC). The proposed approach leverages femtosecond laser ablation and fragmentation in liquids for the fabrication of water-dispersed ultra-stable spherical TMDC nanoparticles (NPs) of variable size (5 – 250 nm). Such nanoparticles demonstrate exciting optical and electronic properties inherited from the TMDC crystals, due to preserved crystalline structure, which offers a unique combination of pronounced excitonic response and high refractive index value, making possible a strong concentration of electromagnetic field in nanoparticles.
