本論文採用雙通後向之超螢光光源，也就是1550nm C頻帶之溫度補償之摻鉺光纖寬頻光源，模擬其置於太空極端環境中，欲即時監控寬頻光源之平均波長與輸出光功率之變化，以便作適當應對與處置。第二章分別作文獻探討超螢光光源的主要核心技術與即時監控的光路設計，針對抗輻射與溫度之穩定光源為目標。第三章介紹寬頻譜之超螢光光源的組成重要元件，再來透過在光源輸出端之前添加一段摻鉺光纖吸收體，此吸收體會抑制1530 nm波段，其抑制效果取決於摻雜濃度與長，實驗結果證實成功地藉由選擇適當的摻雜濃度與長度來進行光源平坦度優化。
第四章為光源穩定度分析，在溫度穩定性方面，分析光源輸出頻譜圖後發現，未受寬頻譜光柵濾除的1530 nm波段為影響環境溫度變化之平均波長穩定性主要原因，可藉由吸收體進行優化抑制，實驗結果證實成功地優化整體系統架構之平均波長穩定性。輻射穩定性方面，光源受到輻射所引起之衰減，可藉由寬頻譜光柵作為反射元件，以進行光退火機制達成修復作用。第五章以1530 nm波段作為參考光源之即時監控設計，由於1530 nm波段對於1550波段的寬頻光源之平均波長有著相依關係，因此在即時監控架構中添加寬頻譜光柵將1530 nm波段反射出來加以驗證，在環境溫度變化下(攝氏-10 oC至80 oC)，實驗結果證實除了高溫區間(70 -80 oC)外,其餘溫度點在量測1530 nm波段之平均功率對於主要光源之平均波長呈現良好的對應關係，並且具有良好的線性度。

In this thesis, we studied temperature-compensating erbium-doped fiber (EDF) broadband light source for extreme environments (temperature, radiation) application. The light source operating in 1550 nm band is in backward pumping scheme, double-pass scheme. The average power and mean wavelength of broadband light source were real-time monitoring to confirm its reliability.　In Chapter 2, several prior works for broadband light source are studied and discussed. Some optic design and real-time monitoring skills are referred and modified in our thesis to achieve anti-radiation and temperature stability goals for the proposed broadband light source. Later, we introduced some important components for investigation the broadband superfluorescent source. Then, we put a piece of EDF as absorber before the output end. The EDF absorber may suppress the amplified spontaneous emission (ASE) of 1530 nm band to some extend by selecting appropriate length and doping concentration for EDF. Results shows that flattened broadband spectrum could be obtained.
Then, we analyzed and discussed the stability of the light source in Chapter 4. In thermal stability, 1530 nm amplified spontaneous emission (ASE) in superfluorescence fiber source may affect the average thermal stability of mean wavelength and should be suppressed. Fortunately, the task could be realized by adding a piece of absorber and the thermal stability of mean wavelength could be improved successfully. In Gamma radiation experiment, the broadband superfluorescent source may result in fiber loss by radiation. Nevertheless, broadband fiber Bragg grating (BBFBG) may help to create photo-annealing effect to against the radiation induced attenuation (RIA).　In Chapter 5, using 1530 nm ASE as the reference light source for real-time monitoring is proposed. The reason is because average power for 1530 nm band and 1550 nm are dependent with each other. Therefore, we used 1530 nm BBFBG as reflector to bounce the 1530 nm ASE as reference light source for real-time monitoring the 1550 nm band broadband superfluorescent source. Result shows the mean wavelength for 1550 nm band will shift to shorter wavelength when the bounced power in 1530 nm region increase accordingly. The relationship between them is quite linear in between temperature region of -10 to 60 oC.
