Abstract
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.
