ABSTRACT:
A photo-imprinting stand for the making of Bragg networks on a photosensitive waveguide or on optical fibers is used to obtain an apodization of the grating. The stand has a dynamic masking device having a variable surface with respect to the beam of UV rays during the photo-imprinting carried out by insolation of the guide using a beam of ultra-violet rays and an interferometry device. Application to the apodization of Bragg gratings.
