本論文探討摻鉺超螢光光源的特性、光退火效應、穩定性以及Sagnac干涉儀的應用。利用經碳纖維複合材料溫度補償後的寬頻譜光纖光柵，形成複行後向的光源架構進行光源特性量測。比較使用HG980B1與AG980H兩種摻鉺光纖的光源特性，以不同長度加入光源架構中進行量測，並以輸出功率、平均波長及3 dB頻寬進行探討。5 m HG980B1的輸出表現較佳，輸出功率達10.65 dBm、平均波長1549.3 nm、3 dB頻寬為16.92 nm。光退火效應部分，將HG980B1和AG980H進行總輻射劑量200 krad的60Co輻射照射，利用637 nm雷射對受輻摻鉺光纖進行輻射損耗修復，並藉由980 nm寬頻譜光源量測摻鉺光纖的吸收頻譜變化來探討修復輻射損耗的光退火效應。結果兩種摻鉺光纖的輻射損耗皆可被637 nm雷射修復，以AG980H的輻射損耗較高但修復的程度較多，在980 nm波段的損耗降低了12.71 dB。探討光源的溫度與即時輻射穩定性，使用複行後向光源架構，溫度穩定性量測光源在溫度範圍0 oC至70 oC內的輸出特性，以5 m HG980B1的結果較佳，其輸出功率變動小於0.12 dB，平均波長穩定性小於2 ppm/oC，3 dB頻寬變動小於2.2 %。即時輻射穩定性量測，將5 m的HG980B1照射總劑量200 krad的60Co輻射，並在光源架構中加入10 mW的637 nm雷射作為光退火光源進行即時輻射損耗修復。在4.55 小時、200 krad照射下，輸出功率變動小於1.31 dB，平均波長變化量為178.67 ppm，3 dB頻寬變動為0.7 %。Sagnac干涉儀的應用部分，使用2x2光纖耦合器並根據Sagnac效應設計水平感測架構，利用5 m HG980B1的複行後向光源作為感測光源，並以長度分別為3 m、4 m及5 m的Sagnac干涉儀進行水平感測，隨著角度旋轉偏移，Sagnac干涉儀的輸出功率呈現近似餘弦波的變化，以5 m Sagnac干涉儀的結果較為穩定，在順時針90o及逆時針90o的角度變化中，功率的線性變化約為0.05 mW/o。

In this thesis, the characteristics of super-fluorescent fiber source (SFS), the recovery of photo-annealing effect and the application of fiber optic gyroscope (FOG) were discussed. The main scheme used here was a double-pass backward SFS (DPB-SFS) based on a broadband fiber Bragg grating (BFBG), which is temperature-compensated by carbon fiber reinforced plastic (CFRP). First, two types of Erbium-doped fiber (EDF), HG980 B1 and AG980H, in different lengths were used in the DPB-SFS. The properties of DPB-SFS using both types of EDFs were studied in their output power, mean-wavelength and 3 dB bandwidth. The best output power, mean-wavelength and 3 dB bandwidth were 10.65 dBm, 1549.3 nm and 16.92 nm, respectively, using 5 m EDF (HG980 B1). Then, we discussed the photo-annealing effect. The EDFs were exposed in 60Co gamma-radiation with a total dose of 200 krad. Because the molecular bonding of EDF would be damaged by the radiation, a 637 nm red light laser was used to recovery the radiation-induced loss. The properties of radiation-induced loss and recovery were characterized by measuring the absorption spectra of EDFs which were pumped by a 980 nm broadband light source. Results showed that both types of EDF could be photo-annealed by the 637 nm red light laser. The AG980H EDF suffered greater loss than the other, but the loss could be healed up to 12.71 dB after photo-annealed. After that, the thermal and real-time radiation stabilities of DPB-SFS were discussed. In this part, we discussed the thermal stability by using 5 m EDF (HG980B1) and the temperature ranging from 0 to 70 oC. The measured variation of output power, mean-wavelength and 3 dB bandwidth were 0.12 dB, 2 ppm/oC and 2.2 %, respectively. To verify real-time radiation stability, a 5 m HG980B1 EDF was set in the radiation chamber for 4.55-hour 60Co gamma-radiation exposure with a total dose of 200 krad. Again, a 637 nm red light laser was used to the DPB-SFS for in-time recovery of radiation-induced loss. The measured variation of output power, mean-wavelength and 3 dB bandwidth were 1.31 dB, 178.67 ppm and 0.7 %, respectively. Finally, for the investigation of Sagnac interferometer, the horizontal sensing based on Sagnac effect was introduced, and the DPB-SFS with 5 m HG980B1 EDF was used as sensing light source. Three interferometer schemes based on 2x2 fiber couplers in different lengths of EDF (3 m, 4 m and 5m) were investigated. The results showed that the variation of output power was periodic up and down in cosine function when the rotation angles varys from 0o to 90o both on clockwise and counter-clockwise direction. Taking 5 m interferometer for example; the slope on linear region is 0.05 mW power per rotation angle.
