Patent number: 10340656Abstract: A semiconductor laser source includes a structured layer formed on a substrate made of silicon and having an upper face. The structured layer includes a passive optical component chosen from the group composed of an optical reflector and a waveguide. The component is encapsulated in silica or produced on a silica layer. At least one pad extends from a lower face of the structured layer, making direct contact with the substrate made of silicon, to an upper face flush with the upper face of the structured layer. The pad is produced entirely from silicon nitride, in order to form a thermal bridge through the structured layer. An optical amplifier is bonded directly above the passive optical component and partially to the upper face of the pad in order to dissipate the heat that it generates to the substrate made of silicon.Type: GrantFiled: June 29, 2017Date of Patent: July 2, 2019Assignee: Commissariat A L'Energie Atomique et aux Energies AlternativesInventors: Corrado Sciancalepore, Marco Casale
