This work is devoted to the study of the drift of the operating point of integrated-optical circuits based on proton-exchange waveguides in lithium niobate crystal with a recovered structure of the near-surface layer. Recovered of the damaged near-surface layer of lithium niobate wafer was carried out using pre-annealing at temperature of 500 °C. Drift of operating point is characterized by a constant change in the optical output power of the integrated-optical circuits when a bias voltage is applied to the electrodes or temperature changes. Recovered of the damaged near-surface layer of lithium niobate wafer leads to a decrease in the short-term and long-term drifts of the operating point of integrated-optical circuits. Crystal structure factor was investigated on the drift of operating point of integrated-optical circuits based on lithium niobate crystal.

In this work, the complete fabrication process which combines Proton Exchange (PE) and Reverse Proton Exchange (RPE) in Neodymium doped LiNbO3 channel waveguides is reported. To produce the PE-RPE channel waveguides the fabrication of dielectric SiO2 masks had to be implemented. For this propose, we adopted a technique based on the Ion Plating Plasma Assisted Deposition of SiO2 followed by the standard ultraviolet photolithographic patterning. On the other hand, we determined the main optical and spectroscopic properties of Nd3+ ions in the channel waveguides including the study of the lifetime as function as the polarisation.
