Abstract

The invention discloses a transparent glass-ceramic material. The composition formula of the transparent glass-ceramic material is 20GeS 2 •35Ga 2 S 3 • 45CsCl, which is obtained from Cl-doped Ge-Ga-S chalcogenide glass material through microcrystallization heat treatment, and Cl is doped into Ge-Ga-S chalcogenide glass material in the form of CsCl compound. The transmittance of the transparent glass-ceramic material disclosed by the invention is 80-85%, and the third-order nonlinear refractive index can reach 1.47×10 ‑18 m 2 / w. The transparent glass-ceramic material of the present invention has high permeability, good chemical stability and thermal stability, fast optical response, and has the advantages of easy fiber formation and film formation, and easy mechanical processing. The switch (All optical switch AOS) device is an excellent non-resonant nonlinear optical material, which will play a better practical value in the future optical field.

Description

technical field [0001] The invention relates to a transparent glass ceramic, in particular to a transparent glass-ceramic material and a preparation method thereof. Background technique [0002] With the rapid development of today's information technology, optoelectronic technology is increasingly showing its core position, and the development of new nonlinear optical materials is an important part of the development of optoelectronic technology. Glass is transparent and optically isotropic at most wavelengths, so it generally only shows third-order nonlinearity, and glass has high thermal and chemical stability. More importantly, glass is easy to prepare and process, so it is used as a A nonlinear optical material is very attractive. In many glass systems, the outermost electron cloud of chalcogen elements (S, Se, Te) in chalcogenide glasses is prone to distortion under the induction of strong light field, so its third-order nonlinear performance is superior to that of ord...
