摘要
The invention relates to a process for the production of gratings inscribed photorefractive of the type bragg gratings, from a waveguide having a planar substrate coated with a film of fluorinated glass pzg type, characterized in that said film comprises one or several doping elements chosen from the group constituted by an effective amount of rare earth ions, in particular this * * 3 +, * * 2 + and in that said film is subjected to apodization plot by irradiation with a radiation in the field of the ultraviolet. & br / the invention also relates to an optical component (19), comprising a substrate (9) coated with a film (18) is carried out according to the process of the invention.
