“…To decode the sensing signal form FBG sensor, the broadband amplified spontaneous emission (ASE) light sources [8] and wavelength-tunable fiber lasers based on erbium-doped fiber amplifier (EDFA) were utilized extensively [9][10][11][12]. However, the ASE light source would result in the low optical signal to noise ratio (OSNR) and high power consumption.…”

In this work, we propose and investigate an intelligent fiber Bragg grating (FBG)-based sensor system in which the proposed stabilized and wavelength-tunable single-longitudinalmode erbium-doped fiber laser can improve the sensing accuracy of wavelength-divisionmultiplexing multiple FBG sensors in a longer fiber transmission distance. Moreover, we also demonstrate the proposed sensor architecture to enhance the FBG capacity for sensing strain and temperature, simultaneously.

“…In general, the capacity of FBG-based sensor system would be restricted due to the available bandwidth of C-band (1530-1560 nm) ASE and EDF-based laser sources [11][12][13].…”
