“…Particularly, in their application as sensors recently have been used in various areas of interest, such as chemical, acoustic waves, pressure and temperature measurements [1][2][3][4][5][6][7][8][9][10].Moreover design of sensor systems using Bragg grating optical fiber (FBG) as temperature or strain sensors have applications in different areas. FBGs has been widely accepted because of their optical fiber compatibility, construction features that make them lightweight, small and their low sensitivity to electromagnetic interference feature [11,12].…”

In this paper a linear cavity Erbium doped fiber (EDF) laser based in a fiber Bragg grating (FBG) and a fiber optical loop mirror with a high birefringence fiber in the loop (Hi-Bi FOLM) is used as a strain sensor. The Fabry-Perot cavity is formed by the FBG and the Hi-Bi FOLM, used as a measurement system of strain variations produced on the FBG, used as a strain sensor device. Usually, fiber laser sensor experimental setups determine the measured variable magnitude by using of an optical spectrum analyzer (OSA). Hi-Bi FOLM transmission spectrum wavelength displacement by fiber loop temperature variations measurement can be an attractive application exploiting the characteristics of FOLM transmission spectrum behavior due to Hi-Bi fiber loop temperature variations to determine the FBG strain applied through the maximal optical power monitoring by simple use of a photodetector and a temperature meter.

“…Doped fiber macro bend sensors are relatively few and used to measure parameters such as temperature, deformation, and pressure [6]- [11]. A fiber laser pressure sensor utilizing erbium doped fiber as the amplification medium in a linear cavity resonator was reported earlier in [8]. The fiber laser pressure sensor has characteristics of simple configuration, low threshold power, stable output power, and high signal to noise ratio.…”

Investigation of Bending Sensitivity in Partially Doped Core Fiber for Sensing Applications

A fiber based high sensitive bend sensor is proposed and demonstrated using a uniquely designed partially doped core fiber (PDCF). The fabrication method of PDCF with two core regions, namely an undoped outer region with a diameter of ∼9.5 µm encompassing a doped, inner core region with a diameter of 4.00 µm is explained. The mechanism of bending effect in proposed PDCF and the experimental setup for amplified spontaneous emission (ASE) based sensor and fiber laser based sensor is illustrated. For ASE sensor, the higher ASE power level loss as the spooling radius is reduced from 20 to 3 cm is measured. The gain peak shift to shorter wavelength with respect to the decrease of the spooling radius from 20 to 3 cm due to higher bending loss at smaller bending radius is observed. The results are in agreement with overlap factor variation of PDCF. As expected from ASE peaks variation, the fiber laser sensor spectral operation is changed from 1539 to 1530 nm range. This phenomenon is due to higher mode field diameter of longer wavelength and result of optical filtering at longer wavelengths. The experimental results showed the output of the ASE is also highly stable, with no observable variation in the power output over a measurement period of 1 h. The PDCF is also temperature insensitive.Index Terms-Optical sensors, partially doped core fiber, fiber laser sensor. 1530-437X
