Abstract

The invention discloses a method for preparing a composite thin film material with optical switch and photocuring functions. Through improved sol-gel technology combined with low-temperature organic-inorganic composite technology, azo is simultaneously introduced into the titanium dioxide-based organic-inorganic composite material. A titanium dioxide-based organic-inorganic composite optical waveguide material with optical switching performance, photocuring function, and excellent optical waveguide performance was prepared by using small molecules of benzene and organic photosensitive functional groups. The preparation process is simple, the production cost is low, and mass production can be realized. In addition, a multifunctional composite planar optical waveguide material with a thickness of several microns and an adjustable refractive index can be obtained at low temperature. In view of the photocuring function of the composite film, micro-optical components can be directly prepared on the composite film by optical lithography, ultraviolet soft embossing and other methods. It has very important applications in the fields of photonics and optoelectronic device preparation.

Description

technical field [0001] The invention relates to the preparation of an organic-inorganic composite thin film material, in particular to a method for preparing a composite thin film material with optical switch and light curing functions. Background technique [0002] Micro-optical components are important optical components in integrated optics, which play an important role in imaging, collimation, coupling, and chromatic aberration correction, wavefront shape control and other applications. With the gradual and rapid development of micro-optics, especially the increasing interest of scientists in the research of integrated optics, the demand for micro-optics components has greatly increased. At present, the production technology of micro-optical elements is relatively mature. However, due to the expensive equipment and complicated process, the application of micro-optical elements, especially in civilian products, is greatly restricted due to price factors. As my country be...
