摘要

本篇論文研究利用三種不同波長激發光源，藉由不同激發光方向以及改變拉曼、摻鉺光纖放大器相對位置，所組成三種混合型拉曼／摻鉺光纖之寬頻放大器。利用第一級放大器激發光源因受激散射後，泵激所殘留部份的能量將再次導入第二級放大器，作為第二級放大器放大器泵激使用，藉以提升放大效能。因而可以涵蓋C+L band頻寬，且針對不同架構之間的增益平坦度、激發光功率和雜訊指數做比較與分析，獲得頻寬為93nm之寬頻放大器且無使用增益平坦濾波器，以及增益平坦度即以符合±1dB標準以內。且在不變條件下，增寬三泵激光源間隔之配置長達約34∼40nm，可以並且避免四波混合效應對系統造成不利的因素與影響。

In this thesis, we propose to use three types of Raman/EDFA hybrid amplifiers with different pumping direction and different order of EDFA and Raman amplifier will be discussed. In order to improve efficiency of power conversion, therefore, a wide-band hybrid amplifier, which can cover C-and L-band, will play an important role in the fiber communication system. The second amplifier was implanted into the Residual pump in this hybrid amplifier which was resulted from the stimulated scattering of first amplifier to be the pump of the second amplifier.Currently; we have built the wide-band hybrid optical amplifiers. We get maintaining excellent gain flatteness and bandwidth of 93 nm without any gain equalization filters. Note the performance comparison in this thesis under the three amplifier configurations in terms of gain, pump power, noise figure (NF). As suggested this thesis, a wide-space pump’s scheme is one of the possible solutions for reducing four-wave mixing (FWM) effect.
