Abstract

The copper exchange effects in waveguides containing different H_xLi_1-xNbO₃ phases are investigated. We have used x-ray diffraction, m-line spectroscopy in the visible, near UV and IR regions and holographic characterization methods. The crucial dependence of holographic sensitivity on phase composition has been found to be the specific feature of Cu:H:LiNbO₃ waveguides. It is established, that the main peculiarities of optical and photorefractive properties are caused by simultaneous formation of Cu⁺ defects and (OH^--Cu⁺) pair defects.
