Abstract :
A study of the effect of ambient water vapour on the stability of LiNbO3 Mach-Zehnder optical waveguide devices is reported. It is shown using both a conventional stability measurement technique and a novel voltage-stressing technique that the presence of water vapour degrades considerably the stability of these devices.
