Abstract

The side-writing of Bragg gratings in fibers by exposure to a periodic UV intensity pattern is discussed. The spectral characteristics of gratings in depressed index fiber are described including the formation of higher-order reflection bands and coupling to cladding modes. Exposure requirements are compared with photosensitivity measurements of the refractive index change induced by individual KrF laser pulses. Commercial germaosilicate thin film waveguides are also found to be photosensitive. Results are presented on UV-induced lateral wave confinement in H₂-loaded film and grating formation in standard buried channel guides.
