Abstract
Optical fiber Bragg grating (FBG) arrays can be fabricated in-line on a draw tower using the phase mask technique. On the FBG arrays, some grating spectrum distortions, for example, asymmetric side lobes or deformed side lobes, low extinction ratio of the main reflection peak and comb filter-type peaks, can be observed. We collected different distorted reflectance spectra of the in-line fabricated FBGs and compared them with the simulated spectra of FBGs. By comparing the experimental and theoretical FBG spectra, it is found that the different kinds of spectral distortions are caused by phase shifting, asymmetric apodization and nonlinear chirp.
