Abstract :
To ensure the quality and repeatability of electro-optic devices, it is necessary to be able to characterise the material before processing. We propose two methods of characterisation: a prism-coupling experiment and the use of second harmonics. These two methods can be used together to obtain very sensitive measurements of the optical homogeneity of LiNbO3 boules and substrates.
