中文摘要 |
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幫激雷射的單幫激組態之放大自發性輻射光 纖光源的特性。我們用1480 nm的幫激雷射幫激摻鉺光 纖,選擇適當的光纖長度,藉由調整幫激光源功率,分析 光纖輻射的ASE特性。我們討論的架構有前向單行(SPF)、 後向單行(SPB)、前向復行(DPF)和後向復行(DPB)四種光 源,比較光源的輸出功率、平均波長、光源線寬和幫激效 益。實驗結果顯示DPF架構在低反射量8%時,摻鉺光纖輻 射的ASE具有13.8 mW的輸出功率,平均波長為1585.7 nm,光源線寬為40.9 nm,幫激效益為13.8%,此為四種架 構中較佳的光源特性。 |
Abstract |
In this thesis, we investigate the single-pumped L-band (1570-1610 nm) amplified spontaneous emission fiber source by employing 1480 nm single pumping configuration. Using the 1480 nm-pumped laser, we chose the adequate fiber length and adjusted the pump power to optimize the characteristics of the ASE source. The characteristics are experimentally examined and compared in terms of the output power, mean wavelength, spectral linewidth, and pumping conversion efficiency in four configurations with single-pass forward (SPF), single-pass backward (SPB), double-pass forward (DPF), and double-pass backward (DPB) structures. Among them, the DPF configuration with low mirror reflectance of 8% is the better one to be an L-band ASE fiber source with output power of 13.8 mW, mean wavelength of 1585.7 nm, spectral linewidth of 40.9 nm and pumping efficiency of 13.8%. |
