摘要: 在本論文中我們利用自己建立的理論模型來分析以及設計DFB光纖雷射,為了希望雷射為單模輸出,在DFB光纖光柵上引入了 相位移( phase-shift),並藉由調整 相位移的位置來讓雷射達到較佳的工作效率。我們也實際製作DFB光纖雷射,利用實驗室所建立的寫入光柵系統來製作 相位移光柵,目前的成果以可達到接近單模的雷射輸出,邊模壓縮比(side-mode suppression ratio)能達到27dB左右,且只有一個邊模存在。
In this thesis we study and design the DFB fiber lasers, by constructing the required theoretical tools. The -phase-shifted fiber grating structures are utilized for achieving single-mode lasing and the position of the phase-shifted is adjusted for achieving optimum efficiency. We also actually fabricate DFB fiber lasers by utilizing the fiber grating exposure system in our lab. Single-mode lasing has been almost achieved with side-mode suppression ratio=27dB and only one side mode is present.
