本論文利用10Gbps電吸收調變器探討光纖雷射於波長轉換之特性與應用。內容主要包含運用到的物理機制、電吸收調變器特性與波長轉換特性的量測分析,以及自製光纖雷射光源的架構,並利用波長轉換結果比較可調式光纖雷射與可調式半導體雷射,並分析產生差異的原因。
首先,以實驗探討外加偏壓與幫浦功率對元件特性影響等靜態的量測,接著利用兩種不同光源於探針光源分別進行波長轉換,並探討轉換後所量測的眼形圖特性與誤碼率特性,最後再將兩種結果拿來作比較,歸納出自製雷射光源的優缺點。
使用自製光纖雷射於探針光源進行波長轉換,其轉換範圍可達20nm,約為此電吸收調變器可操作範圍的66%,熄滅比最高可達5.07dB,抖動最低達21.91ps,Q值最高達10.58,功率補償量最低僅需3.25dB,以上結果顯示自製光纖雷射已突破傳統光纖雷射應用上限制的圍籬,將有機會更進ㄧ步躍升於全光網路的應用中。
In this thesis, we demonstrate all-optical wavelength conversion using the electro-absorption modulator at 10Gbps and the optical fiber laser in wavelength conversion. The topics include the physical mechanism and characteristics of electro-absorption modulator, wavelength conversion, and make the special structure of the fiber laser source. Furthermore, we compare Tunable Semiconductor Laser Source(TSLS) with Tunable Fiber Laser Source(TFLS) on wavelength conversion and analyze the causes of the differences.
At first, measurements of the static state were carried out by varying the parameters of EA modulator such as bias voltage and optical pumping power. We carry out the wavelength conversion by using two different light sources each as the probe light source and study their characteristics of the eye diagrams and BER and sum up the advantages and the faults of TFLS.
The range of wavelength conversion is 20nm, the highest ER is 5.07dB, the lowest jitter is -22ps, the highest Q value is 10.58 and the lowest power penalty is 3.25dB, when self-making fiber laser is as probe light source in the wavelength conversion. We get a result that the Self-making fiber laser has broken the limit of the application in the traditions of the fiber lasers and expect that it will be used in the all-optical network.
