Abstract
(EN)
A method for fabricating a thermal optical heating element capable of adjusting refractive index of an optical waveguide is disclosed. A silicon block is initially formed on a cladding layer on a silicon substrate. The silicon block is located in close proximity to an optical waveguide. A cobalt layer is deposited on the silicon block. The silicon block is then annealed to cause the cobalt layer to react with the silicon block to form a cobalt suicide layer. The silicon block is again annealed to cause the cobalt suicide layer to transform into a cobalt di-silicide layer.

L'invention porte sur un procédé de fabrication d'un élément chauffant optique thermique capable d'ajuster l'indice de réfraction d'un guide d'ondes optiques. Un bloc de silicium est initialement formé sur une couche d'un substrat de silicium. Le bloc de silicium est disposé à proximité étroite du guide d'ondes optiques. Une couche de cobalt est déposée sur le bloc de silicium. Le bloc de silicium est ensuite recuit afin d'amener la couche de cobalt à réagir avec le bloc de silicium pour former une couche de siliciure de cobalt. Le bloc de silicium est à nouveau recuit pour amener la couche de siliciure de cobalt à se transformer en une couche de disiliciure de cobalt.
