Abstract

The optical properties and both unstrained lattice constants in the high-index zinc-substituted lithium tantalate waveguides are determined depending on exchange and annealing conditions. The LiTaO₃-ZnTa₂O₆ system clearly exhibits a complex structural chemistry. The two distinct phases have been observed. The dependences of the extraordinary and ordinary indices change on the lattice parameters of the unstrained single crystalline Li_1-xZn_x/₂TaO₃ solid solutions in both observed phases were obtained.
