Comprehensive Dataset of Linear and Nonlinear Optical Properties of Chalcogenide Glasses from Literature

This dataset compiles reported linear and nonlinear optical metrics of various chalcogenide glass compositions collected from the scientific literature. It includes data for both planar and rib waveguide structures, thin films, and other device geometries fabricated using different deposition and patterning methods. The dataset covers a broad range of compositions (e.g., As–S, As–Se, Ge–Se systems, and hybrid chalcogenide/oxide structures) and summarises experimentally measured parameters such as:Refractive index (n0) and band gap energyPropagation and coupling lossesEffective mode area and mode typeNonlinear refractive index (n2)Nonlinear coefficients (γ)Stimulated Brillouin scattering (SBS) and Raman gain coefficientsSupercontinuum generation (SCG) bandwidthsQuality factors (Q-loaded and Q-intrinsic)Fabrication details (e.g., PLD, RIE, photolithography)The dataset is intended as a reference database for researchers working on integrated nonlinear photonics, Brillouin and Raman scattering, supercontinuum generation, and optical material design based on chalcogenide glasses. Each entry is referenced to its original publication, allowing cross-checking of the source and experimental context.
