Fiber optic sensor technology based on Brillouin scattering is rapidly spreading due to quantities is great precision measured such as temperature, strain and vibration in the long haul distributed sensing. In this study Brillouin scattering has been analyzed in the single mode fiber. An experimental setup has been done using OptiSystem 12.0, and Brillouin(More)
In this study, a Fiber Bragg Grating (FBG) based multiple temperature sensor array is designed using a conventional laser source that has 6 nm bandwidth in lowest signal level. This design is simulated in OptSim optical software. The simulation is conducted to observe 5 FBG's response to the temperature change individually. The temperature incident on the(More)
In this study, one of the important characteristic of type I and type II Quantum Cascade Lasers (QCLs) that is optical gain which is a function of injection current and wavelength is implemented using Adaptive Neuro-Fuzzy Inference System (ANFIS) architecture. The proposed simple and useful models are in very good agreement when compared with the(More)
Fiber Bragg Gratings (FBG) draw considerable interests for their specifications as low sizes, easy mounting, remote sensing, sufficient to sense more than one or more parameters in the same line and low cost when used several. The main specification of FBG is that they reflect measured parameter directly and linearly in the centre Bragg wavelength. In this(More)
In this study, Passive Edge Filter was designed using Erbium Doped Fiber. When this design was done, simulation was performed to monitor gain changes with respect to −5, −10, − 15, −20 dBm input signal power and varying lengths of I6 EDF which design by FibeCore company. As a result of the simulation, we have experimentally(More)
In this study, fiber lengths of each stage of the three stages L band erbium doped fiber amplifier (L-EDFA) and the pump laser power are optimized to achieve the maximum gain, the minimum noise figure and the minimum gain ripple. It is obtained on an average 34.7-37.1 dB gain, 6.28-6.0 dB noise figure, and 2.13-2.28 dB gain ripple along all L band for the(More)
In this study, stress-induced Brillouin scattering was experimentally analyzed by the weight applied to a specific point of the classical single mode fiber cable. A Brillouin optical time domain analysis (BOTDA) test system was developed for frequency shifts according to different weights applied. For different weights, the frequency values of the scattered(More)
