Abstract :
The DC drift in Ti-diffused LiNbO3 optical waveguide devices were remarkably reduced by adding an ion exchange process before the deposition of buffer layers in the device fabrication. The ion exchange was performed by heating the Ti-diffused LiNbO3 substrate in molten alkaline metal nitrates. Lithium nitrate was found most effective
