Twisted Fiber Bragg Gratings as a Polarization-Insensitive Element [PDF]
SensorsThis work proposes an original method for fabricating Bragg gratings using the point-by-point technique with femtosecond laser radiation, which minimizes the polarization dependence of the gratings’ optical response. The method is based on inscribing the

Chebyshev apodized fiber Bragg gratings. [PDF]
Sci Prog, 2021 In this paper, a new apodized fiber Bragg grating (FBG) structure, the Chebyshev apodization, is proposed. The Chebyshev polynomial distribution has been widely used for the optimal design of antennas and filters, but it has not been used for designing FBGs.
