“…A detailed description of the experimental setup used to analyze the diffracted light of fiber Bragg grating around and along the fiber length can be found in Ref. 8 . A Toshiba TCD1304DG linear CCD image sensor consisting of 3648 elements with 8-μm-long pixel resolution was employed as a detector.…”

“…In all these applications, the typical optical responses of the fiber Bragg grating are a reflection and transmission spectrum. However, with the growing diversity in applications of fiber Bragg grating in certain sensing [2][3][4] and spectrometric fields, [5][6][7][8][9] there is an increasing need for and importance of practical techniques involved in the manufacturing process providing the spatial information of the grating.…”

This research introduces a new non-destructive technique for the characterization of fiber Bragg gratings (FBGs) based on the analysis of the FBG diffraction profile via measuring its asymmetry and intensity. This approach enables the determination of such FBG parameters as an off-axis displacement, aberrations of the focusing system, outcoupling efficiency of refractive index modulation, grating length, and grating order. This proposed technique can significantly improve quality control in FBG manufacturing. The applicability of this technique is demonstrated on different types of fiber Bragg gratings written by point-by-point femtosecond laser writing.

In this Letter, we proposed a new technique for point-by-point fiber Bragg grating (FBG) writing in a static fiber by using a spatial light modulator to control the position of the focal point inside the fiber core. Various types of short-length FBGs (uniform, phase-shifted, and apodized) were demonstrated by this inscription technique. Moreover, the capability to tailor the transverse dimension of a grating pitch from a single point to more complex shapes, such as a wide plane covering a whole fiber core or a transverse ring, was shown.
