Les réseaux de Bragg photoinscrits dans les fibres optiques sont devenus indispensables pour l'égalisation du gain des amplificateurs, la stabilisation en longueur d'onde des pompes ou des sources, et pour les lasers à fibre. Leurs atouts majeurs sont de faibles pertes d'insertion, une très faible sensibilité à la polarisation et une conception extrêmement flexible. Ces atouts en font également des candidats très attractifs pour les applications de filtrage complexe ou de compensation de dispersion chromatique fine. Cet article décrit brièvement les différentes familles de réseaux de Bragg ainsi que quelques exemples d'applications dans les télécommunications optiques.
Bragg gratings photoimprinted in optical fibers have become essential for flattening the gain of amplifiers, stabilizing the wavelength of pumps or sources, and for fiber lasers. Advantages are low insertion loss, very low polarization sensitivity and an extremely flexible design. Those advantages make gratings also very attractive candidates for applications of complex filtering or precise chromatic dispersion compensation. This article briefly describes the different types of Bragg gratings as well as several examples of applications in optical telecommunications.
