【摘要】：光子晶體光纖(PCF)具有許多普通光纖不具有的特性,隨著光子晶體光纖基礎(chǔ)研究的不斷深入,制作工藝日趨成熟,越來(lái)越多的不同種類的光子晶體光纖不斷涌現(xiàn)。在光纖傳輸系統(tǒng)中,為了增加系統(tǒng)的集成化和全光化,光子晶體光纖的使用愈加頻繁,其對(duì)現(xiàn)代集成光學(xué)的意義也愈加凸顯。本文設(shè)計(jì)了一種新型的基于碲酸鹽玻璃的單芯光子晶體光纖,可以實(shí)現(xiàn)不同波長(zhǎng)的光的分離,利用全矢量有限元法對(duì)其特性進(jìn)行了理論分析;制作了一種M-Z光纖傳感器,使用單芯光子晶體光纖與單模光纖錯(cuò)芯熔接,將其對(duì)溫度較不敏感的特性進(jìn)行了改進(jìn),對(duì)光子晶體光纖進(jìn)行了溫敏液體的填充,使得其對(duì)溫度靈敏度提高,完成對(duì)溫度和折射率變量的傳感。主要內(nèi)容包括:1.概述了光子晶體光纖的基本原理和特性,介紹了光子晶體光纖的制作和主要應(yīng)用及研究現(xiàn)狀。2.給出了常用的對(duì)光子晶體光纖進(jìn)行研究的方法,重點(diǎn)介紹了全矢量有限元法和用該方法進(jìn)行仿真計(jì)算的軟件COMSOL Multiphysics,并且集中闡述了光子晶體光纖對(duì)于傳感領(lǐng)域的應(yīng)用。3.設(shè)計(jì)了一種基于碲酸鹽玻璃的單芯光子晶體光纖,采用全矢量有限元法對(duì)其特性進(jìn)行了研究。結(jié)果表明,此種分束器可以實(shí)現(xiàn)1.3μm和1.55μm波長(zhǎng)的光的分離,使其分別在x和y偏振方向上傳播。當(dāng)光纖長(zhǎng)度為15mm時(shí),1.3μm和1.55μm處的串?dāng)_值分別低至-45.1d B和-40.2d B,小于-20d B的帶寬分別為44.2nm和67.1nm。4.制作了一種新型的錯(cuò)芯結(jié)構(gòu)的M-Z型傳感器,通過(guò)將光子晶體光纖與單模光纖錯(cuò)芯熔接,來(lái)制作傳感單元,對(duì)溫度和折射率變量進(jìn)行傳感。當(dāng)折射率的改變量為0.05時(shí),波谷由1578.1nm向右漂移至1583.2nm,對(duì)折射率的靈敏度為102nm/RIU;由于光子晶體光纖對(duì)溫度具有相當(dāng)大的穩(wěn)定性,當(dāng)溫度從75℃變?yōu)?5℃時(shí),波長(zhǎng)從1578nm向右漂移至1578.4nm,靈敏度為-3-8′10 nm/℃。5.針對(duì)第四章所制作的溫度和折射率傳感器,為了改進(jìn)其對(duì)溫度的相對(duì)不敏感性,對(duì)光子晶體光纖進(jìn)行了填充,在其中填充了有較高的熱光系數(shù)的物質(zhì)—乙醇,可以很大的提升對(duì)溫度的敏感度,當(dāng)溫度由75℃下降到25℃時(shí),波谷由1525.7nm右移到1576.1nm,靈敏度大約為-1.008nm/℃。當(dāng)折射率的改變量為0.05時(shí),波谷由1551.3nm向右漂移至1555.4nm,折射率靈敏度大約為80.3nm/RIU。
[Abstract]:Photonic crystal fiber (PCF) has the characteristics of many ordinary optical fiber with photonic crystal fiber, with basic research deepening, production technology matures, more and more kinds of photonic crystal fibers emerge. In optical fiber transmission system, in order to increase the system integration and development, the use of more photonic crystal fiber frequently, the significance of modern integrated optics has become even more prominent. This paper describes the design of a single core photonic crystal fiber based on tellurite glass model, can separate the different wavelengths of light, its characteristics are studied by using the full vector finite element method; making a M-Z optical fiber sensor, single core photonic crystal fiber and single-mode fiber core welding will be wrong, it is not sensitive to the temperature characteristic is improved, the photonic crystal fiber were filled with temperature sensitive liquid, which make it to The temperature sensitivity, sensing of variable temperature and refractive index. The main contents include: 1. summarized the basic principle and characteristics of photonic crystal fiber, introduces the fabrication of photonic crystal fiber and the main application and research status of.2. gives the commonly used method of photonic crystal fiber were studied, mainly introduced the full vector finite element method and simulation software COMSOL Multiphysics with this method, and focuses on the application of.3. photonic crystal fiber for sensing the design of a single core photonic crystal fiber based on tellurite glass, using a full vector finite element method was used to study its characteristics. The results show that the separation of the beam splitter can be achieved 1.3 m and 1.55 m wavelengths of light, which were spread in the X and Y polarization direction. When the fiber length is 15mm, crosstalk between 1.3 m and 1.55 m respectively as low as -45.1d B and -40.2d B, -20d is less than the bandwidth of B were 44.2nm and 67.1nm.4. made M-Z a new sensor fault core structure, the photonic crystal fiber and single mode fiber fault core welding, to produce a sensing unit, the temperature and refractive index sensing variables. When the refractive index change is 0.05 when the trough from 1578.1nm to 1583.2nm on the right shift, the sensitivity of refractive index is 102nm/RIU; the photonic crystal fiber has considerable stability to temperature, when the temperature from 75 degrees to 25 degrees, the wavelength from 1578nm to 1578.4nm for the right drift, temperature sensitivity and refractive index of the -3-8 '10 nm/ C.5. made in fourth the rate of sensors, in order to improve the temperature of the relative sensitivity of photonic crystal fiber were filled in, which are filled with high calorescence coefficient material - ethanol, can greatly enhance the sensitivity to temperature When the temperature drops from 75 to 25 degrees, the trough moves from 1525.7nm to 1576.1nm, and the sensitivity is about -1.008nm/ -1.008nm/. When the change of refractive index is 0.05, the wave valley moves to 1555.4nm to the right, and the sensitivity of refractive index is about 80.3nm/RIU..
