    Abstract:   近年來,光纖通信產業及光纖感測器技術日益成熟。因光纖小尺寸、低損耗傳輸、不易遭受電磁波及優異的抗惡劣環境之優點,它非常適合於長距離光傳輸與監控線路。儘管電子式感測器有很好的發展,它們大多需要一個就近的電源和一些連接線,這可能導致它們的性能下降,因電磁和雜訊干擾。另外,當處於惡劣環境中,它們是易損壞的。
    Recently, fiber-optic communications and fiber-optic sensor technology have made great progress. Because of the advantages of optical fiber, including small size, low-loss transmission, less susceptible to electromagnetic interference, and excellent immunity to harsh environments, it is very suitable for long-haul optical transmission and monitoring lines. Although the electronic sensors have a good development, they mostly need a nearby power supply and connected wires, which may cause them performance degradation due to electromagnetic and noise interference. In addition, they are damageable when laid in harsh environments.
    In this thesis, the characteristics of optically pumped DFB lasers as temperature sensors have been studied; meanwhile, experimental results have also verified the feasible scheme for implementing the remote temperature monitoring system based on an optically pumped DFB laser.
