Optical Isomerization and Photo-Patternable Properties of GeO2/Ormosils Organic-Inorganic Composite Films Doped with Azobenzene

GeO2/organically modified silane (ormosils) organic-inorganic composite films containing azobenzene were prepared by combining sol-gel technology and spin coating method. Optical waveguide properties including the refractive index thickness of characterized using a prism coupling instrument. Surface morphology photochemical investigated atomic force microscope Fourier transform infrared spectrometer. Results indicate that have smooth neat surface, excellent optical performance. Photo-isomerization studied UV–Vis spectrophotometer. switching performance was also under alternating exposure 365 nm ultraviolet light 410 visible light. Finally, strip waveguides microlens arrays built in through UV soft imprint technique. Based on above results, we believe are promising candidates for micro-nano optics photonic applications, which would allow directly integrating data storage devices onto single chip.
