Patent number: 7480423Abstract: An all-fiber, phase controlled interferometer device is disclosed as well as its method of manufacture. This device is suitable for use in an optical DPSK demodulation system. It is comprised of two optical fiber couplers, each having two input and two output ports and two branches between the couplers of unequal length. The couplers have a splicing ratio of 50% over the wavelength operating range of the device. The two branches between the couplers are shaped to provide one bit of delay between the branches and are also shaped to make a compact device. Also, the two branches are formed in such a manner as to minimize birefringence in the device. In addition, a fiber heater is provided to heat the longer branch so as to obtain phase control of the interferometer. The method of producing such a device is also disclosed.Type: GrantFiled: February 16, 2006Date of Patent: January 20, 2009Assignee: ITF Laboratories Inc.Inventors: François Seguin, Denis-Alexandre Brulotte, Julien Tremblay, Claude Deslisle, Alexandre Wetter, Denis Bouchard, François Gonthier

Patent number: 7373070Abstract: A package for an optical fiber device is disclosed. It has a high thermal conductivity packaging substrate surrounding the optical fiber device and has adhesive bonds at each end anchoring the optical fiber device to the substrate. The adhesive bonds are made of a material that has high transparency in damp heat as well as a high glass transition temperature and is capable of withstanding temperatures of over 100° C. The packaging substrate has a high absorption capacity and a CTE in relation to the CTE of the adhesive bond, such as to compensate for any variation in the adhesive bond due to temperature variations. This allows to limit mechanical stress in the optical fiber device within the package.Type: GrantFiled: January 22, 2007Date of Patent: May 13, 2008Assignee: ITF Laboratories Inc.Inventors: Alexandre Wetter, François Seguin, Lilian Martineau, Mathieu Faucher

Patent number: 7046875Abstract: An optical coupler is provided. It has a bundle of multimode fibers with a few-mode fiber in its centre. Such bundle is fused at one end which is the output end for the signal that is transmitted by the few-mode fiber. To make the coupler, this output end of the bundle is aligned and spliced with a large area core double clad fiber while preserving the modal content of the feed-through. A method for making such optical coupler is also provided. It includes the steps of bundling a central few-mode fiber with a plurality of multimode fibers and then fusing one end of such bundle and aligning it and splicing with a large core double clad fiber, while preserving fundamental mode transmission from one to the other.Type: GrantFiled: October 29, 2003Date of Patent: May 16, 2006Assignees: ITF Technologies Optiques Inc., ITF Optical Technologies Inc.Inventors: François Gonthier, Lilian Martineau, François Seguin, Alain Villeneuve, Mathieu Faucher, Nawfel Azami, Marc Garneau

Publication number: 20050274825Abstract: A fire-hose nozzle with a body (1) having a first end intended to be connected to a source of fluid under pressure and a second end supporting a hollow head (3) in which are provided a tube (8) and a stem (9) extending coaxially in the tube. The stem supports at its end situated opposite the body (1) an end-piece (10) delimiting with the tube an adjustable jet (11) intended to give passage to the fluid passing through the body and the hollow head. A regulator (14) is provided for automatically varying the dimensions of the jet (11) so that the fluid flow exiting therefrom remains constant irrespective of the pressure of the fluid.Type: ApplicationFiled: June 9, 2005Publication date: December 15, 2005Applicant: ST.-MIHIEL S.A.S.Inventor: Jean-Francois Seguin

Patent number: 6974266Abstract: A packaging device for protectively enclosing an optical component in a substantially clean and anhydrous environment without imparting undue mechanical stresses on the optical component and adjacent segments of optical fiber coupled thereto. An intermediate component is used in combination with a sealing material for sealing the fiber aperture of a protective housing while allowing an optical fiber to extend therethrough. The protective housing is made out of a material having a coefficient of thermal expansion that closely matches that of the optical fiber. A chain of material CTE that includes the CTE of the intermediate component is used in order to circumvent the need for a sealing material having a high melting temperature. The packaging device is also designed so as to reduce water ingress by optimizing the configuration of the sealing component and adjacent structures.Type: GrantFiled: August 7, 2003Date of Patent: December 13, 2005Assignee: ITF Optical Technologies Inc.Inventors: François Seguin, Pierre Martineau, Denis-Alexandre Brulotte, Patrick Cigana, Pascal Octeau, Xavier Daxhelet, Sébastien Allard
