A process of poling a silica material such as an optical fiber whereby electro- optic non-linearities are induced so that the material can function as a phase modulator and switch in optical communications applications. The poling is effected at an elevated temperature on the order of 450 °C or higher, using an electric field on the order of 800 V/µm or higher for a period of time in the range of one minute to several tens of minutes.

Cette invention concerne un procédé de polarisation d'un matériau de type silice tel que celui constituant une fibre optique, qui permet d'induire des non linéarités électro-optiques telles que ledit matériau peut fonctionner en tant que modulateur et commutateur de phase dans des applications de communications optiques. La polarisation est effectuée à température élevée, supérieure ou égale à 450 DEG C, au moyen d'un champ électrique supérieur ou égal à 800 V/ mu m, pendant un laps de temps compris entre une minute et plusieurs dizaines de minutes.
