【摘要】： 與無機光波導(dǎo)材料相比較,聚合物光波導(dǎo)材料具有結(jié)構(gòu)性能易于調(diào)控、制備工藝簡單、成本低等優(yōu)點,而且聚合物材料可以與不同基底材料匹配,有利于和其它光電子器件的集成。已成為未來全光網(wǎng)絡(luò)系統(tǒng)的重要選材之一。但是聚合物材料也有其自身的缺點,比如,光損耗高,耐熱性差等。 聚硅氧烷兼具有機聚合物材料的易加工和無機材料的耐高溫等多種特性,成為近年來研究的熱點。但是目前由于其固化周期長和光學(xué)損耗大等缺陷,限制了其應(yīng)用。為了降低聚硅氧烷材料的本征光吸收損耗,同時為了使其與新型納米壓印技術(shù)相匹配,本文采用非水解溶膠-凝膠法制備了可紫外光固化的液態(tài)聚硅氧烷光波導(dǎo)材料。詳細研究了其合成技術(shù)和光學(xué)性能,為其進一步應(yīng)用打下基礎(chǔ)。 本文以二苯基硅二醇,苯基三甲氧基硅烷,甲基丙烯酰氧丙基三甲氧基硅烷為反應(yīng)前體,制備出了含苯基的聚硅氧烷樹脂。以二苯基硅二醇,十二氟庚基丙基三甲氧基硅烷,甲基丙烯酰氧丙基三甲氧基硅烷為反應(yīng)前體,制備出了含氟聚硅氧烷樹脂。系統(tǒng)研究了反應(yīng)時間和催化劑用量等對聚硅氧烷結(jié)構(gòu)和性能的影響,及聚硅氧烷樹脂的光學(xué)和熱力學(xué)性能、固化、旋涂加工技術(shù)。 結(jié)果表明,兩種聚硅氧烷樹脂均具有較高的折射率,苯基聚硅氧烷樹脂折射率達到了1.54,含氟聚硅氧烷樹脂的折射率為1.52。兩者的雙折射均低于0.0005。苯基聚硅氧烷樹脂通過延長固化時間使得其1550nm波段的光學(xué)損耗降低到0.36dB·cm-1。UV固化和熱固化后,苯基聚硅氧烷在空氣中的熱分解溫度在320℃以上,含氟聚硅氧烷的熱分解溫度在250℃以上,表現(xiàn)出優(yōu)異的耐熱性能。
[Abstract]:Compared with inorganic optical waveguide materials, polymer optical waveguide materials have the advantages of easy structure control, simple preparation process and low cost, and the polymer materials can match different substrate materials. Facilitate the integration with other optoelectronic devices. It has become one of the important material selection of all optical network system in the future. However, polymer materials also have their own shortcomings, such as high light loss, poor heat resistance and so on. Polysiloxane has become a hot research area in recent years because of its many properties such as easy processing of organic polymer materials and high temperature resistance of inorganic materials. However, its application is limited by its long curing period and high optical loss. In order to reduce the intrinsic light absorption loss of polysiloxane materials and to match the new nano-imprint technology, a UV-curable liquid polysiloxane optical waveguide material was prepared by unhydrolyzed sol-gel method. The synthesis technology and optical properties were studied in detail, which laid a foundation for its further application. In this paper, polysiloxane resin containing phenyl was prepared by using diphenyl silyl, phenyl trimethoxy silane and methacryloxy propyl trimethoxy silane as reaction precursors. Fluorinated polysiloxane resin was prepared by using diphenyl silyl diol dodecyl heptyl trimethoxysilane and methacryloxy propyl trimethoxysilane as reaction precursors. The effects of reaction time and amount of catalyst on the structure and properties of polysiloxane, the optical and thermodynamic properties of polysiloxane resin, curing and spin-coating technology were systematically studied. The results show that both polysiloxane resins have high refractive index. The refractive index of phenyl polysiloxane resin and fluorinated polysiloxane resin is 1.54 and 1.52respectively. The birefringence of both is less than 0.0005. By prolonging the curing time, the optical loss in 1550nm band of phenyl polysiloxane resin is reduced to that of 0.36dB cm-1.UV curing and heat curing. The thermal decomposition temperature of phenyl polysiloxane in air is over 320 鈩，
