Abstract
Optical component having a plurality of Bragg gratings and process for the production of said component. According to the invention, an optical component is formed comprising a light guide and Bragg gratings which are formed in the guide and have predetermined Bragg wavelengths. This guide comprises a single diffraction grating (16) and zones (24, 26, 28, 30) associated with the Bragg gratings and. The zone have optical indices chosen so as to obtain, in cooperation with the diffraction grating, the Bragg wavelengths.
