“…The proposed sensor has sensitivity about two times greater than the figure of 0.18 THz∕MPa reported for the Bragg grating embedded in a laminated composite [16] and almost three orders of magnitude lower than the record high sensitivity of 240 THz∕MPa reported recently for rocking filters [11]. The most important drawback of the proposed sensing concept is the limitation of the operation range to pressure at which the fiber phase birefringence becomes null.…”

We studied vector frequency conversion in externally tuned microstructured fibers for applications as a novel, nonlinear fiber-optic sensor. We investigated both experimentally and numerically a possibility of shifting vector and scalar modulation instability gain bands by pressure-induced changes in the linear properties of a microstructured fiber. Our results show that polarization-dependent vector nonlinear processes sensitive to variation of fiber group velocity difference (group birefringence) exhibit a clear advantage for pressure-sensing applications compared with scalar nonlinear processes only sensitive to group velocity dispersion changes. Analytical predictions and numerical simulations confirm our measurement results.

“…Since FBGs are very small, once they are bound to the host materials, the strain distribution of FBGs is determined by the mechanical property of these host materials. In a previous paper [4], we have Mass reported one novel method of fabricating a high pressure FBG sensor with carbon fiber reinforced laminates (CFRLs). In that scheme, multi layers of CFRLs and epoxy are sandwiched to be host materials of FBG to achieve a broad measurement range and good sensitivity.…”

In this paper, we present a study of detecting the hysteresis effect in strain-stress curve of carbon fiber reinforced materials by Fiber Bragg Grating technology. By calculating the dissipative energy density contoured by hysteresis loops, this method can be further applied in detecting the cracks and fatigue of carbon fiber reinforced laminates. In contrast to the traditional sensors, such FBG sensors have numerous merits, such as small size, immunity to Electromagnetic Interference and easy installation into the carbon fiber reinforced laminates. This method can also be extended into monitoring other materials which also exhibit hysteresis effects in their strain-stress curves.

“…In 1993, Xu et al [1] showed that the pressure sensitivity of a bare FBG is only À 3.04 pm/MPa. Thereafter, many approaches for enhancing the sensitivity of FBG pressure sensors were proposed [2][3][4][5][6]. However, the measurement range of the FBG with polymer [3] is small due to the polymer's mechanical properties.…”

“…The methods mentioned above are also hardly used for harsh environments and special conditions, such as deep sea drilling. The FBG and carbon fiber laminated composite [6] can compensate for these shortcomings, and it has high sensitivity, large measurement range and relatively small size. Even now, this pressure sensor cannot be installed in some extremely narrow space, where just a bare FBG can be installed.…”
