摘要：
This work describes new types of optical sensing systems based on Depressed Cladding Erbium Doped Fiber (DC-EDF). Due to the amplification characteristics developed for S-Band uses, this sensing system has high sensitivity, high dynamic range and wide bandwidth. It can be used to monitor static parameters such as force, pressure, displacement and dynamic parameters used in acoustics and vibrations. Two types of sensing systems with different approaches have been studied: the amplifier and the laser sensor. We describe the performance of these sensing systems in S band (1490 and 1510 nm) in static and dynamic conditions. We also appointed for some sensing applications for many areas of interest, such as, electric energy and civil engineering.
