Patent number: 8761549Abstract: A component, device and improved electro-optical modulation system for increasing compactness, favoring the adaptation of optical and electrical waves, and a method of fabrication. Such a component exhibits a waveguide architecture devised so that the length of the path followed by the luminous flux exhibits, with the length of the path traversed by the electrical control signal, a determined difference for decreasing or compensating for the difference in the speeds of propagation of the luminous flux and of the electrical signal. In particular, the modulation zone includes a path of the luminous flux winding around itself and successively crossing at least two indentations emanating from at least two of these control elements. It thus exhibits a length greater than that traversed by the electrical signal, for example between a first and a second region of interaction between this control signal and this luminous flux.Type: GrantFiled: September 29, 2010Date of Patent: June 24, 2014Assignees: Universite Paris Sud 11, Centre National de la Recherche ScientifiqueInventors: Gilles Rasigade, Laurent Vivien, Delphine Marris-Morini

Patent number: 8415185Abstract: In a process for fabrication of an optical slot waveguide on silicon, a thin single-crystal silicon film is deposited on a substrate covered with an insulating buried layer; a local thermal oxidation is carried out over the entire depth of the thin single-crystal silicon film in order to form an insulating oxidized strip extending along the desired path of the waveguide; an insulating or semi-insulating layer is deposited on the silicon film; two openings having vertical sidewalls are excavated over the entire thickness of this insulating or semi-insulating layer, said openings being separated by a narrow gap constituting an insulating or semi-insulating vertical wall that will be the material of the slot; single-crystal silicon is grown in the openings and right to the edges of the insulating or semi-insulating wall; and then the upper part of the silicon is etched in order to complete the geometry of the waveguide.Type: GrantFiled: December 13, 2011Date of Patent: April 9, 2013Assignees: Commissariat a l'Energie Atomique et aux Energies Alternatives, Alcatel Lucent, Centre National de la Recherche Scientifique, Universite Paris-SUD 11Inventors: Jean-Marc Fedeli, Guang-Hua Duan, Delphine Marris-Morini, Gilles Rasigade, Laurent Vivien, Melissa Ziebell

Patent number: 7657146Abstract: An optoelectronic controller for regulating an optical signal. The controller includes a ridge or rib waveguide in an SOI-type substrate. The controller also includes an active zone formed by a plurality of thin layers of silicon. The layers are either N+ type doped or P+ type doped. The zone is defined between an N+ doped zone and a P+ doped zone which together form a PIN diode. The optoelectronic controller is all-silicon and operates by carrier desertion.Type: GrantFiled: March 29, 2005Date of Patent: February 2, 2010Assignees: Universite Paris-SUD, Centre National de la Recherche Scientifique - CNRSInventors: Suzanne Laval, Delphine Marris, Éric Cassan, Daniel Pascal
