【摘要】：光子晶體光纖(photonic crystal fiber,PCF)是新一代基于光子晶體技術(shù)進而發(fā)展起來的光纖。這類光纖具有很多優(yōu)點,如:低損耗特性、無截止單模特性、靈活的色散特性、極強的雙折射效應(yīng)、可控的非線性以及可進行微結(jié)構(gòu)設(shè)計改造等,隨著光纖光子晶體光纖的理論日趨成熟,工藝制造日益完善,光子晶體光纖傳感器的應(yīng)用研究也逐漸成為熱點。本論文研究的側(cè)重點是空氣孔填充有液晶的光子晶體光纖,在傳感領(lǐng)域的技術(shù)探討。通過對液晶材料的特性分析,可知其有折射率隨電場,溫度變化而變化的特性。并結(jié)合雙波導(dǎo)耦合模原理,對液晶填充后形成的光波導(dǎo)與光纖纖芯這種雙波導(dǎo)模型,進行分析,發(fā)現(xiàn)其發(fā)生相位匹配的規(guī)律。并探討檢測的方法和其優(yōu)缺點。實驗主要集中在液晶填充的工藝方法的研究和光纖傳感器對外加電場、溫度感應(yīng)效果,并提出利用飛秒激光器進行工藝制備的全新高效方案,為光子晶體光纖傳感器的制造工藝發(fā)展進行探索。同時對光子晶體光纖傳感器在液晶填充物方面的特性及優(yōu)勢,進行了相關(guān)的研究,為光子晶體光纖傳感器在相關(guān)領(lǐng)域的發(fā)展做出微薄貢獻。
[Abstract]:Photonic crystal fiber (photonic crystal fiber, PCF) is a new generation of optical fiber based on photonic crystal technology and development. This kind of fiber has many advantages, such as low loss characteristics, characteristics of endless single mode, the dispersion characteristics of flexible, strong birefringence, controllable nonlinear and micro structure design transformation with the development of optical fiber, photonic crystal fiber theory matures, manufacturing process improvement, application research of photonic crystal fiber sensor has been a hot issue. This paper focuses on air hole photonic crystal fiber is filled with liquid crystal, to explore in the field of sensing technology. Through the analysis of the material characteristics of liquid crystal, the refraction the rate varies with the electric field, the characteristics of temperature change. Combined with the dual waveguide coupled mode principle, on the formation of liquid crystal filled waveguide and fiber core of the double waveguide model Analysis found that the phase matching rules. And to explore the detection methods and their advantages and disadvantages. The experiment mainly process in liquid crystal filling research and optical fiber sensor external electric field, temperature effect, and puts forward the new preparation process scheme of femtosecond laser, photonic crystal fiber manufacturing process development the sensor was explored. The characteristics and advantages of photonic crystal fiber sensor in liquid crystal filling area, carried out relevant research, and make contributions to the development of micro thin photonic crystal fiber sensor in the related field.
