A novel method for creating linearly and nonlinearly chirped fiber Bragg gratings

摘要

We propose a novel and flexible method for controlling the chirp rate of a linearly chirped fiber Bragg grating (FBG) and nonlinearly chirped FBG by adhering a uniform FBG onto a plastic plate with a pre-calculated curvature and applying an axial force on the plate. The center wavelength shift was measured to be only 0.1 mn, which is small compared with the previously reported techniques. The dispersions of the linearly chirped FBG and the nonlinearly chirped FBG were measured to be about 1200 psm and 125 psmm, respectively, and the bandwidth of the chirped FBG was about 0.5 nm.
