WebMar 3, 2024 · Coherent Optical Fiber Sensing Based on a Frequency Shifting Loop Abstract: In this paper, the proof-of-concept of an optical fiber sensing technique based on a frequency shifting loop (FSL) is proposed. The system combines both a refreshing rate of the sensing measurement in the MHz range and a centimetric spatial resolution. WebErbium-doped Fiber Laser. Er-doped fiber lasers (EDFLs) can be viewed as EDFAs operating in the particular regime where coherent oscillation of ASE occurs due to some feedback means. A standard definition could be the following: EDFLs are used as sources for coherent light signal generation, while EDFAs are used as wave-wave amplifiers for ...
