Design and Feasibility Study of Tunable Fiber Bragg Grating Laser Sources in Advanced Long-Range Sensors

In this study, a tunable laser source was designed and simulated using
OptiSystem software, based on credible similar articles analysis, by using a
laser pump and a Raman amplifier. The simulation results showed that
tunable laser sources based on fiber Bragg gratings can be used for
monitoring targeted devices up to a distance of 300 kilometers from the
monitoring station. Moreover, by serially placing fiber Bragg gratings and
using a multi-wavelength, the reflected signals were transmitted through a
single-mode fiber for monitoring at the transmission station. In the
conducted experiments, it was feasible to obtain a reasonable output power
from fiber Bragg grating sensors using a 1-watt 980-nanometer laser source.
Therefore, remote control and monitoring can be performed at far distances
from the monitoring station. Consequently, the hypotheses of the study,
including the design of tunable laser sources and their use in fiber Bragg
grating sensors, the use of tunable laser sources in advanced long-range
sensors, and the design and simulation of tunable laser sources based on
various fiber Bragg gratings in advanced long-range sensors, were
confirmed.
