Patent

CA 2396500

The present invention provides an athermalized organic-containing overclad integrated planar optical waveguide circuit device in which thermal induced shifting of channel wavelengths is minimized. The organic-containing overclad material is combined with a silica or doped silica glass material in the form of a local overclad, a bi-layer overclad, or a hybrid overclad. The organic- containing overclad material is a polymer or a sol-gel material.

L'invention concerne un dispositif de circuit guide d'onde optique, plan, comprenant une gaine supplémentaire contenant un matériau organique insensible aux variations thermiques et dans lequel le décalage des longueurs d'onde de canal -induit par les variations thermiques- est réduit à un minimum. Le matériau de cette gaine supplémentaire est combiné à une silice ou à un matériau de verre de silice dopée, sous la forme d'une gaine supplémentaire locale, d'une gaine supplémentaire à deux couches ou d'une gaine supplémentaire hybride. Le matériau de cette gaine supplémentaire contenant le matériau organique est un polymère ou un matériau sol-gel.
