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.

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.
