    We propose a flexible method for fabricating complex fiber grating structures based on sequential writing for fiber gratings with polarization control of the UV source beam. Pure apodized as well as arbitrary phase-shifted fiber Bragg gratings (FBGs) can be fabricated in a single scan. Experimental examples of raised-cos(2) apodized and dispersionless FBG filters are given to demonstrate the feasibility of this method. (C) 2004 Optical Society of America.
