CA 2336627

A thermo-optic semiconductor device has one semiconductor region providing an optical waveguide and an adjacent semiconductor region providing a resistive heater between two doped regions, current may be passed through the resistive heater within the adjacent semiconductor region to heat it and thereby vary the optical characteristics of the waveguide.

L'invention concerne un dispositif à semi-conducteur thermo-optique comportant une zone à semiconducteur qui présente un guide d'onde optique, et une zone à semiconducteur adjacente qui comporte une résistance chauffante entre deux zones dopées. Un courant peut traverser la résistance chauffante, dans la zone à semiconducteur adjacente, pour chauffer celle-ci, moyennant quoi on fait varier les caractéristiques optiques du guide d'onde.
