Abstract :
This paper presents the influence of the phase state of proton exchanged (PE) LiNbO3 and LiTaO3 waveguides on the second-order optical nonlinearity by using reflected second harmonic generation (SHG) measurements from the polished waveguide end face in different HxLi1-xNbO3 and HxLi1-xTaO3 phases: as-exchanged and annealed proton-exchanged (APE) waveguides, high-temperature proton-exchanged (HTPE) waveguides, as well as reverse proton exchanged (RPE) waveguides, and proton exchanged waveguides in stoichiometric and MgO-doped LiNbO3 crystals.
