本論文重點為以環型光纖雷射注入法布里-比洛雷射二極體來提供雙向傳輸使用,文中以實驗驗證C波帶可調式光纖雷射注入法布里-比洛雷射二極體,應用在分波多工存取網路中,可調式光纖雷射不但可提供用戶端的下行訊號,還可作為用戶端之注入法布里-比洛雷射二極體的注入光源,以提供上行光源,使上下行訊號為同一波長,可以更有效利用C波帶頻寬。文中所用可調式光纖雷射,可調範圍可達30nm,功率的變動量少於0.6dB;我們的下行訊號調變10Gbps NRZ碼2 -1 虛擬隨機序列,上行訊號則為1.25Gbps NRZ碼2 -1 虛擬隨機序列,上下行訊號分別傳送25公里單模光纖,功率補償值皆約1dB;文中並實驗展示此系統的Detuning範圍與分析注入條件。
In this thesis, a study is made of the Fabry–Pérot laser diode (FP-LDs) injected-locked by fiber ring laser in bidirectional network. It is demonstrated that the C-band fiber ring laser and injection-locked FP-LD can be applied to wavelength-division-multiplexing access networks. The fiber laser not only generates downstream data traffic but also serves as the injection light source for the upstream FP-LD. The downstream and upstream data are transmitted by the same wavelength and thus made the bandwidth allocation efficiently.
The fiber ring laser has a tunable range of 30 nm in the C-band and a power fluctuation smaller than 0.6 dB. For 10-Gbps downstream and 1.25-Gbps upstream transmissions over 25-km Single-mode fiber, power penalties about 1 dB. Moreover, analyses of the detuning range and injection conditions for a better performance are also made in this thesis.
