Abstract

In this study, we report on the thermal regeneration of Type-I tilted fiber Bragg gratings produced in hydrogen loaded single-mode optical fiber (SMF28). Both 193 nm excimer laser and 266 nm femtosecond pulses were used to inscribe the gratings through phase mask technique. We show that the regenerated cladding modes resist, without degradation, up to 910 ◦C and show the same refractometric properties as in non-regenerated tilted gratings.
