Influence of the Proton Concentration on the Properties of the LiNbO3 and LiTaO3 Crystals.
Abstract
In the proposal we wrote one year ago, the work plan for the first year was to compare between as exchanged waveguides and annealed waveguides presenting the same index profiles in order to determine if the proton concentration in a given phase is fixed or depends on the fabrication conditions, extra protons, sometimes called 'interstitial protons' being introduced in some cases. We planned to do this on LiTaO3 where we knew the phase diagram of the exchanged layers. But today, the phase diagram of the LiNbO3 is also known, so this study will be transferred to this crystal, which presents more interest for the application we are presently considering: the realization of an Integrated Optical Parametric Oscillator, but the work plan will be exactly the same.
