| 中文摘要 | 本论文的研究目的在于探索适合用于离子交换法制备集成光波导器件的饵掺杂玻璃基质材料。通过研究不同玻璃组分对玻璃样品的化学稗定性、热稳定性、光谱性质以及激光性质的影响，开发新型光波导器件用磷酸盐玻璃和啼酸盐玻璃基质材料。论文首先在引言中概括了集成光波导器件用掺饵玻璃材料研究的目的和意义，接着在文献综述中介绍了稀土离子掺杂玻璃理论、掺饵磷酸盐玻璃和掺饵蹄酸盐玻璃的研究进展，随后介绍了掺饵玻璃光波导器件的结构和工作原理、制备工艺以及研究进展。论文第二章介绍了本论文的研究方法，详细介绍了玻璃样品制备、性能测试、玻璃光波导制备以及光谱理论分析与计算、离子交换原理、激光谱理论等。论文第三章研究了不同A1203、BaO、Na2O、Li2O、La2O3、Y2Q3和AlF3等玻璃组分对磷酸盐玻璃化学稳定性、物理性质以及光谱性质的影响，实验发现：高AbO3含量有利于提高玻璃样品的化学稳定性；碱金属氧化物Na2O和Li2O对玻璃样品的化学稳定性不利；对于含Y2O3和La2O3较多的玻璃样品，Y2O3由于其离子半径较小，对玻璃样品的析晶性能影响不大，但引入离子半径较大的La2O3却明显降低了玻璃样品的热稳定性。最后，研制出适于离子交换法制备光波导器件的wM／YE一2和wMLi磷酸盐玻璃材料，其中w树YE一2用于Ag+-Na＋离子交换，wMLi用于Ag+-Li+离子交换。wM／YE-2玻璃中饵离子的峰值发射截面为o．72xl10-20cm2，wMLi玻璃中饵离子的峰值发射截面为o．65xlo-20cm2。通过水浴和盐浴失重测试发现WM/YE-2玻璃和WMLi玻璃具有优良的化学稳定性，优于Kigre公司的MM-1玻璃和Schott公司的IOG-1玻璃。论文第四章首先分析了几种含Na＋离子的蹄酸盐玻璃的物理性质、热性质和光谱性质，初步确定磅-钨-钠玻璃比较适合用于离子交换法制备光波导器件。蹄-钨-钠玻璃的转变温度高于通常的离子交换温度，饵离子在蹄-钨-钠玻璃中具有较大的受激发射截面和较宽的荧光半高宽。随后，分别研究了wo3、GeO2、B2o3I等玻璃组分对蹄一钨一钠玻璃性质的影响，实验发现：随着WO3含量的增加，玻璃样品的密度、折射率、转变温度Tg和Tx一Tg均增大，但光谱性质变化不大；随着Geo2含量的增加，玻璃样品的密度和折射率减小，转变温度Tg和Tx一Tg均增大，同样光谱性质变化不大；随着B2o3含量的增加，玻璃样品中饵离子的1．5μm波段荧光强度逐渐减弱，荧光半高宽减小，饵离子的4115尼能级荧光寿命从3．gms降低为2．smso最后，综合以上实验结果，研制了一个用于Ag+-Na＋离子交换法制备光波导器件的掺饵磅酸盐玻璃基质材料wMTe，玻璃转变温度几和析晶开始温度Tx分别为377℃和488℃，折射率nd为2．0148，其中饵离子的浓度为2．0xl020cm一，峰值发射截面为9．lxl0-21cm2，FwHM为65nm。论文第五章研究了不同离子交换条件，熔盐组成、温度、时间等参数以及后期处理对光波导性质的影响。·实验发现：熔盐组成为1％AgN03＋99％KNO3时，不同温度、时间条件下均实现了632．8nm的多模光波导，1535nm的单模光波导，光波导的传输损耗均小于ldB/cm；离子交换时间对传输损耗的影响不大，但随着温度升高和熔盐中AgNO3含量的增加，传输损耗有增大的趋势；后期退火处理和二次离子交换使光波导从玻璃表面向玻璃内部移动。采用Ag+-Na＋离子交换在WN/YE-2玻璃基质上成功制备了条状光波导放大器，光波导的传输损耗为0．14dB／cm，通道长度为3．7cm，宽度为7．5μm。单向980nm泵浦时，最大增益为7．sdB，增益系数为2．ldB／cm；双向980nm泵浦时，最大增益15．2dB，增益系数为4．ldB／cm。论文第六章研究了不同饵离子浓度和镜、饵浓度配比对磷酸盐玻璃微片激光器的激光性能影响。采用LD泵浦，室温条件下所用玻璃样品均实现了饵离子的1．53林m连续激光输出。其中，饵离子浓度为4．gx1019ions／cm3，厚度为lmm的玻璃样品表现出最大的斜率效率26％；饵离子浓度为0．99x1019ions／cm3，厚度为2mm的玻璃样品实现了最大的输出功率SOmW。最后是本论文的结论部分，总结了全文的实验研究结果，同时指出了存在的不足和需要补充改进之处。 |
| 英文摘要 | The purpose of this work is to develop novel Erbium doped glass materials for integrated optical waveguide applications. Based on the investigation of dependence of chemical durability, thermal stabilization, spectroscopic and laser properties of glass samples on glass compositions, novel phosphate glass and tellurite glass materials can be developed for optical waveguides. The significance of development of novel Erbium doped glass materials for integrated optical waveguides are summarized in the introduction, and then, the basic theory of Rare-earth doped glass, the review of development of Erbium doped phosphate glass and tellurite glass is also introduced in the Chapter One. In the end of this chapter, the configuration and principle of optical waveguide devices based on glass substrate are introduced. In the second chapter, experiment methods of this thesis are introduced, including glass sample preparation procedures, physical and spectroscopic properties measurements, preparation of glass optical waveguides by ion-exchange, and the spectroscopic parameters calculation using Judd-Ofelt and McCumber theory. In the third chapter, the influences of glass compositions such as AI2O3, BaO, Na20, U2O, La2C>3, Y2O3 and AIF3 on chemical durability, physical and spectroscopic properties of phosphate glass samples were investigated. It was found that AI2O3 is beneficial to glass samples with a good chemical durability, and Na2O, Li2O are deleterious to good chemical durability. For glass samples with a high Y2O3 or La2C>3 content, Y2O3 has no obvious influence on glass sample crystallization performance because of smaller radius of Y3+ ions, but La2C"3 degrades thermal stabilization of glass samples for bigger radius of La3+. Novel phosphate glasses WM/YE-2 and WMLi were subsequently developed. WM/YE-2 was developed for Ag+-Na+ ion-exchange, WMLi was developed for Ag+-Li+ ion-exchange. The peak stimulated emission cross-section of Er3"*" in WM/YE-2 is 0.72x10"20cm2, the peak stimulated emission cross-section of Er3"1" in WMLi is O.SSxKT^cm2. From weight-loss measurements, it was found that WM/YE-2 and WMLi glass have excellent chemical durability, and the chemical durability of WM/YE-2 and WMLi glass is superior to Kigre's MM-1 glass and Schott's IOG-1 glass. In the fourth chapter, from investigation of physical, thermal and spectroscopic properties of several tellurite-based glasses containing Na2O, TeO2-WO3-Na2O glass is determined to be a suitable candidate for development of ion-exchanged optical waveguide substrate materials, and then, the influences of glass compositions such as WO3, GeO2, B2O3 on properties of TeO2-WO3-Na2O glass was studied. It was found that the density, refractive index, glass transformation temperature T% and Tx-T |
