Abstract
Bragg gratings with sidelobe levels 26dB lower than the peak reflectiv ity have been fabricated in standard telecommunication optical fibres by exposure to ultraviolet light through a phase mask with a locally v arying diffraction efficiency. This represents a reduction of 14dB in the sidelobe levels compared to uniform gratings with the same bandwid th and reflectivity.
