摘要：The mos. relev.nt as.ects.related to the phas. mas. dithering/mov.ng method for the fabrication of complex Bragg grating des.gns.are rev.ewed. Details.for experimental implementation of this.technique is.pres.nted, including theoretical analys.s.of the calibration functions.for the correct dither/dis.lacement. Res.lts.from tailored Bragg grating s.ructures.fabricated by this.method are s.own. Apodized Bragg gratings.with modeled s.atial profiles.were implemented, res.lting in s.de mode s.ppres.ion lev.ls.of more than 20 dB in gratings.s.owing trans.is.ion filtering lev.l higher than 30 dB. Chirped gratings.with the s.ectral bandwidth up to 4 nm, π-s.ift and s.mpled Bragg gratings.with equalized peaks.equally s.aced by 0.8 nm （100 GHz） were als. fabricated.
