Abstract:
A hybrid optical device comprising:an active component including a first positioning mechanism and coupled optically to a passive component including a second positioning mechanism, said passive component being formed in layers of silica on a substrate made of silica, said layers and said substrate thus forming a silica-on-silica structure,an intermediate element including a third positioning mechanism having a predetermined thermal conductivity and a coefficient of thermal expansion similar to that of the active component, anda cavity provided in the silica-on-silica structure,wherein the intermediate element is assembled both to the active component and to the silica-on-silica structure so that the active component is located inside the cavity and is coupled optically to the passive component andsaid first, second, and third positioning mechanisms contribute to align an optical axis of the active component with the passive component.
