Theoretical and Experimental Study on Fabrication of Chirped Fiber Gratings Using Lenses and Uniform Mask
Fabrications of chirped fiber gratings using spherical lenses and zero order nulled phase masks are studied theortically and experimentally in details. The results show that this method is suitable for producing fiber gratings with small chirp parameters, and will led to servere unsymmetrical reflection spectra and cladding mode coupling when the chirp parameters of the gratings are relatively large.
