Abstract

We report on how the optical and structural properties of Nd:YAG proton beam written waveguides are modified when they experienced annealing treatments from 50 ° C to 950 ° C . The microstructural changes caused in the vicinity of the nuclear damage region were found to be stable up to 700 ° C , so that higher annealing temperatures lead to a complete waveguide erasing. Before this “erasing” temperature, the partial thermal-induced defect recombination reduces the propagation losses, reaching its minimum value (below 1 dB / cm ) after a 400 ° C thermal annealing.
