Grating Fabrication

The paper presents the results of fiber Bragg gratings fabrication by femtosecond laser radiation using point-by-point and line-by-line inscription methods. The approach makes it possible to fabricate the second and higher diffraction orders fiber Bragg gratings, which can be used as sensitive elements of fiber-optic sensors.

Correction System

The paper reports the inscription of second- and third-order fiber Bragg gratings (FBGs) in single-mode optical fiber (SMF-28e+) via the line-by-line (LbL) and the point-by-point (PbP) methods using femtosecond laser radiation. The use of these methods jointly with based on an automatic spatial deviation correction system is considered. The approach allows to significantly improve spectral characteristics of FBG without the loss of fabrication performance.

Non Linear

A new package for thermally compensating a fiber Bragg grating, which requires less accuracy in positioning the fiber onto the device, is discussed. Experiments show that it can reduce the shift in reflected wavelength from 1575 pm to 78 pm for a temperature change of 120 K. The deformation of the package showed no hysteresis, and the effective thermal compensation is repeatable over many cycles. Furthermore the package also has the potential to give non-linear thermal compensation for fiber Bragg gratings.

Quantitative Results

The main task of the contribution was the estimation of the possibility of using Fiber Bragg Gratings as a mean of measuring the deformation in standard carbon fiber samples at elevated temperatures. The article presents the results of experiments on the measurement of deformations in a carbon sample using Fiber Bragg Gratings on an optical fiber. Deformations were measured in the process of stretching the sample at different temperatures (range from 20 to 140 °C). It is shown that FBGs integrated into the sample material give more stable, reproducible readings, unlike to inlay on the outer surface. It has been established that the use of several FBGs with different sensitivity to temperature or deformation (created by mechanically decoupling the sensor from the sample) makes it possible to compensate the effect of temperature when measuring deformations. The quantitative results of measurements are provided.
