摘要: 本论文的主旨在研究消逝场型光纤主被动元件的材料色散与波导结构的影响及其应用。在消逝场光纤元件的制作上,我们分别使用光纤侧磨及火焰熔锥拉伸技术来研究色散相关之物理现象。在材料色散的研究部分,包括研究因为材料声子能量不匹配所引起的光纤基态模波长截止现象及其于宽频可调光纤长波、短波、带通滤波器、波长可调式环型光纤雷射、S+C+L频带掺铒光纤放大器的应用。此外,我们亦提出绕射泵浦的新方法来改善消逝场掺铒光纤放大器的增益。在波导结构的研究部分,包括研究长作用长度及改变曲率半径对光纤消逝场耦合及色散穿隧效应的影响,以及在无穷单模光子晶体光纤中所引起的高阶模态激发之物理现象。这些应用的原理与架构已详尽的分析与实验验证,上述的成果预期将有助于光纤通讯与感测系统及生医光电的发展。
In this dissertation, we study the material dispersion and the waveguide structure of evanescent wave fiber active and passive components and their applications. The fiber side-polishing and fused-tapering techniques are employed to fabricate evanescent wave fiber components and investigate the dispersion related phenomena. In material dispersion, the material dispersion discrepancy between fiber and dispersive material can induce fundamental-mode cutoff which can be further used to make tunable fiber short/long/band-pass filters, tunable fiber ring lasers, S+C+L band EDFAs, and tunable narrowband channel-dropping filters. Moreover, a novel diffractive-pumping method was proposed to improve evanescent amplification of evanescent wave EDFAs. In waveguide structure, the influences of long interaction and variation of bending curvature on spectral responses and the excitation of higher order modes in side-polished endlessly single-mode photonic crystal fiber were investigated. These investigations and demonstrations will be useful in the fields of fiber-optic communication and sensing systems as well as the applications in biophotonics.
