“…Again, the results show that ion-implanted waveguides essentially maintain their properties while proton-exchanged present a larger deterioration [327]. Cajzl et al [328] reported on the influence of the three waveguide fabrication methods (Ti-diffusion, proton-exchange and ion implantation) on the lattice site of erbium. Angular RBS scans confirm that none of the methods has any measurable influence on the position of the Er.…”

X-ray and neutron diffraction studies succeeded in the 1960s to determine the principal structural properties of congruent lithium niobate. However, the nature of the intrinsic defects related to the non-stoichiometry of this material remained an object of controversial discussion. In addition, the incorporation mechanism for dopants in the crystal lattice, showing a solubility range from about 0.1 mol% for rare earths to 9 mol% for some elements (e.g., Ti and Mg), stayed unresolved. Various different models for the formation of these defect structures were developed and required experimental verification. In this paper, we review the outstanding role of nuclear physics based methods in the process of unveiling the kind of intrinsic defects formed in congruent lithium niobate and the rules governing the incorporation of dopants. Complementary results in the isostructural compound lithium tantalate are reviewed for the case of the ferroelectric-paraelectric phase transition. We focus especially on the use of ion beam analysis under channeling conditions for the direct determination of dopant lattice sites and intrinsic defects and on Perturbed Angular Correlation measurements probing the local environment of dopants in the host lattice yielding independent and complementary information.

“…Lithium niobate has been the longest studied in our group and research on erbium doping of LiNbO 3 can be found in our publications. [86][87][88][89][90] In these studies, a comprehensive study of experimental analyses of erbium-doped LiNbO 3 was done and the results were compared with those of other crystals to investigate the influence of crystal surrounding on the luminescence properties of erbium.…”

“…As a multifunctional optoelectronic material, lithium niobate (LiNbO 3 ) has a wide variety of applications including acousto‐optic modulator, [ 1 ] optical waveguides, [ 2 ] optical parametric oscillator, [ 3 ] and so on. In addition, LiNbO 3 is usually grown from congruent melt ([Li]/[Nb] = 0.946).…”

A series of Sc:Yb:Tm:LiNbO3 crystals with variable Sc3+ (0, 1, 2, and 3 mol%) concentration are grown by the Czochralski method. The effective distribution coefficients of Sc3+, Yb3+, and Tm3+ ions in the Sc:Yb:Tm:LiNbO3 crystals are determined by inductively coupled plasma atomic emission spectrometer. Sc3+ ions distribute uniformly in crystals when Sc3+ concentration reaches up to 3 mol%. The influence of Sc3+ concentration on the dopant occupancy and defect structure of Sc:Yb:Tm:LiNbO3 crystals is investigated by IR transmission spectra. Threshold concentration of Sc3+ ions in Sc:Yb:Tm:LiNbO3 crystals is nearly 3 mol%. By analyzing UV–vis–NIR absorption spectra, absorption property of Sc:Yb:Tm:LiNbO3 crystals is improved by doping Sc3+ ions. Additionally, the Sc:Yb:Tm:LiNbO3 crystals can be pumped by commercially available high power AlGaAs LDs.
