本論文針對長波段放大自發性輻射光纖光源進行研究，探討以1480 nm波段雙向幫激雷射架構下的放大性自發性輻射光纖光源的特性。我們以1480 nm、1490 nm幫激雷射幫激摻鉺光纖，適當的選擇摻鉺光纖的長度，在不同反射率(R)下調整幫激雷射的功率，討論光源的輸出功率、平均波長、線寬、平坦度和功率轉換效率。採用的光源架構有雙前向(FF)、前後向(FB)和後前向(BF)等架構。實驗的結果顯示，前後向架構在摻鉺光纖長度為93 m，反射率為30 ％，幫激組合為(40, 130mW)時，摻鉺光纖的放大性自發性輻射光源具有輸出功率(POUT)71.8 mW、平均波長(λm)為1584.3 nm、光源線寬(Δλ)為41.6 nm、平坦度(ΔP)為1 dB和42.2 ％的功率轉換效益(η)，此為三種架構中具有最佳的光源特性。

In this thesis, we investigate the double-pumped L-band (1570-1610 nm) amplified spontaneous emission (ASE) fiber source by employing the 1480 nm bi-directional pumping configuration. First, we chose the adequate fiber length, and then adjusted the pump power to optimize the characteristics of the ASE source in different reflectance. The characteristics are experimentally examined and compared in terms of output power, mean wavelength, linewidth, flatness and conversion efficiency in three configurations with forward-forward (FF), forward-backward (FB) and backward-forward (BF) structures. In our experiments, FB configuration with EDF length of 93 m and reflectance of 30 ％ is the best one to be an L-band ASE fiber source with an output power(POUT) of 71.8 mW, a mean wavelength(λm) of 1584.3 nm, a linewidth(Δλ) of 41.6 nm, the flatness(ΔP) of 1 dB, and the pump conversion efficiency(η) of 42.2 ％.
