Abstract
A hybrid optical device includes a passive component coupled optically to an active component, the passive component being formed in layers of silica on a substrate made of silica, the layers and the substrate thus forming a silica-on-silica structure. The hybrid optical device includes an intermediate element having good thermal conductivity and a coefficient of thermal expansion similar to that of the active component, wherein the active component is fixed to the intermediate element prior to insertion into the cavity, and the intermediate element is fixed to the structure so that the active component is located inside the cavity and is coupled optically to the passive component.
