The bank of photowriting to the embodiment of the arrays of the bragg grating

摘要

The invention relates to a bank of photowriting for the production of bragg gratings on an optical guide is photosensitive, or on optical fibers, which makes it possible to obtain apodization of the network. According to the invention, the bank includes a masking device dynamic range (10, 50) with a variable surface screw - to - screw of the bundle of uv rays during photowriting carried out by exposure of the said guide by means of a beam of ultraviolet rays and a device for interférométrie.application to the apodization of bragg gratings.
