摘要: 在本論文中我們研究了週期漸變光纖光柵的理論、製作及應用。理論上我 們利用耦合模方程式模擬了光柵鐘形化(apodization)對光纖光柵特性的 影響以及因耦合到輻射模所造成的穿透頻譜變化。在實驗上我們使用週期 漸變相位光罩實際製作出具有高反射率的週期漸變光纖光柵,然後應用此 週期漸變光纖光柵來作色散補償及穿透式窄頻濾波器。我們也利用光纖光 柵製作出窄頻的光纖雷射,藉由調變光纖光柵的週期我們可自由改變光纖 雷射的出波長。 In this thesis we study the modeling, fabrication and application of chirped fiber gratings. In the theoretical side we used the couple-mode equations to simulate the effects of apodization and radiation-mode coupling. In the experiment side we have fabricated high-reflectivity chirped fiber gratings using the chirped phase mask approach. These chirped fiber gratings are then used as dispersion compensators and narrow- linewidth transmission filters. Finally, we also use fiber gratings to build tunable narrow-linewidth transmission filters. Finally, we also use fiber gratings to build tunable narrow- linewidth Er-fiber lasers.
