*** 9632301 Hsu This Phase I STTR project will research and develop novel fiber Fabry-Perot tunable filters (FFP-TFs) based on fluoride fibers (specifically ZBLAN fibers), and the application of FFP-TFs in the generation of high-power, narrow-linewidth, and wavelength-tunable Pr-doped ZBLAN fiber lasers in the 1.3 um wavelength region. Recent major advances in Praseodymium (Pr)-doped fluoride glass fibers have made them the most desirable medium for fiber amplifiers and lasers at 1.3~1m wavelength. The availability of prototype Pr-doped fiber amplifiers for 1.3 um wavelength-division-multiplexing (WDM) has heightened the need for 1.3~m lasers. Commercially available widely-tunable laser sources are typically based on grating-tuned external-cavity semiconductor lasers suitable only for laboratory environment. The requirement for 1.3 um tunable lasers that are fiber-compatible, robust, and cost-effective makes an all-fiber based tunable laser structure the best candidate. These lasers will allow telecommunication systems to access an additional 100nm of frequency spectrum using standard 1.3~m single-mode fibers which have been widely installed throughout the world. In addition, the resultant work will enable broad-based ZBLAN fiber device technology development that can be extended to other wavelength regions, e.g., to tunable upconverted blue-green lasers and mid-IR lasers using appropriate dopants in ZBLAN fibers. Additional applications using such new tunable lasers span from holographic data storage (tunable blue-green lasers) and free space optical communication to spectroscopy and environmental sensing (with tunable mid-IR lasers). ***

*9632301徐氏第一期工程项目将研发基于氟化物光纤的新型光纤法布里-珀罗可调谐滤光器，并将其应用于产生1.3um波长范围内高功率、窄线宽、波长可调的零偏振光纤激光器。掺Pr(Pr)氟化物玻璃光纤的最新进展使其成为1.3~1m波长光纤放大器和激光器最理想的介质。用于1.3 nm波分复用(WDM)的掺Pr光纤放大器样机的问世增加了对1.3~m激光器的需求。商业上可用的宽调谐激光光源通常是基于仅适用于实验室环境的光栅调谐外腔半导体激光器。对1.3um可调谐激光器的要求是与光纤兼容的、坚固耐用的和经济高效的，这使得基于全光纤的可调谐激光器结构成为最佳候选。这些激光器将允许电信系统使用标准的1.3~m单模光纤接入额外100 nm的频谱，这些光纤已在世界各地广泛安装。此外，所产生的工作将使基础广泛的ZBLAN光纤设备技术开发能够扩展到其他波长区域，例如，在ZBLAN光纤中使用适当的掺杂剂来调谐上转换蓝绿激光器和中红外激光器。使用这种新型可调谐激光器的其他应用范围从全息数据存储(可调谐蓝绿色激光器)和自由空间光通信到光谱和环境传感(使用可调谐中红外激光器)。***
