Abstract:

Subject of study. The change in the spectral characteristics of superimposed chirped fiber Bragg gratings during their inscription is analyzed. Aim of study. Investigation of the dynamics of changes in the spectral characteristics of chirped fiber Bragg gratings during inscription is performed. Method. Using a KrF excimer laser system and a Talbot interferometer, the diffractive structures consisting of four chirped Bragg gratings with a period variable in length are inscribed in a standard telecommunication single-mode optical fiber (G.657.A2). During the inscription of the fiber structures, the change in the spectral characteristics is estimated depending on the total irradiation dose. Main results. The dependences of the change in the reflection coefficient, the full width at half maximum of the spectral response, and the Bragg resonance wavelength of each chirped Bragg grating of the superimposed structure on the total dose of irradiation are demonstrated. Numerical values of the spectral characteristics’ modulation are given. Practical significance. The results of the work are important in the field of fiber optics, especially in the develop of fiber-optic devices based on Bragg reflectors. The analysis demonstrates the dependences of the change in the spectral characteristics of fiber structures during inscription. The study can be used to optimize the develop of fiber-optic devices based on superimposed chirped Bragg gratings, which allows achieving the required diffractive structures characteristics with high accuracy.
