A New Method for Fabrication of Chirped Fiber Gratings
-
Abstract
A technique for chirped-period fiber gratings with etching method is reported. An analysis is presented for the behavior of the chirped gratings as a function of wavelength, the angle between the illuminating beams, as well as the position of the gratings. Experimentally, chirped fiber gratings have been etched on the D-fiber. Results obtained are in good agreement with theoretical analysis.
