Paper Abstract

The results of experimental investigations on single crystal growth of lithium niobate for optical purposes are reported. The crystals were grown by the Czochralski method with the use of induction heated equipment type CGS-2 made by Spexon. The thermal system consisted of platinum crucible and active platinum afterheater. To determine the homogeneity and optical quality of single crystals the distribution of birefringence and of refractive indices no and ne were measured. Samples of active elements were prepared and their conoscopic images were checked. On the basis of these elements the electro-optic modulators were made for which extinction ratio and V(lambda /2) were measured. Optoelectronic structures with `cut-off' effect on lithium niobate substrates were also prepared for straight and Y waveguides. The waveguides were obtained by Ti in-diffusion.
