Abstract

Strong regenerated gratings with a maximum grating strength exceeding (40-50) dB are fabricated inside an optical fibre by bulk macro thermal processing ∼900°C using a UV-laser seeded Bragg grating. Further annealing between 1000 and 1100°C leads to a stabilised grating ∼18dB in strength. This suffers no further degradation at 1100°C for the period monitored, over 4 hrs. To determine the potential resolution of this process, two regenerated complex profiles with no phase difference between seed and processed structures is reported. This opens the way for nano-engineering of materials using thermal processing and seed templates.
