  • Dynamic gain equalizing filter
    Patent number: 6873765
    Abstract: A tuneable optical fibre comprising a long-period Bragg grating (5) written in a portion of an optical waveguide (10) comprising a core and an optical cladding (11), characterised in that the portion of the waveguide comprising the grating (5) is at least partially immersed in an external environment consisting of two distinct sections, a first section (1) whose refractive index is higher than that of the optical cladding (11) and a second section (2) whose refractive index is lower than that of the optical cladding (11), the long-period grating being at least partially immersed in one of the said sections so as to almost independently tune the wavelength and/or the contrast of the spectral response of the filter.
    Type: Grant
    Filed: April 14, 2003
    Date of Patent: March 29, 2005
    Assignee: Avanex Corporation
    Inventors: Hedi Labidi, Carlos De Barros, Hervé Loury, Xavier Bonnet, Isabelle Riant, Jean-Jacques Guerin
  • Method of stripping an optical fiber
    Patent number: 6763872
    Abstract: A method of stripping an optical fiber including a silica optical waveguide and a coating to be removed over a portion to be stripped includes making a cut in the coating of the portion to be stripped, depositing a stripping gel on the coating of the portion to be stripped, and cleaning the portion to be stripped to remove the coating and expose the silica of the fiber.
    Type: Grant
    Filed: April 9, 2002
    Date of Patent: July 20, 2004
    Assignee: Avanex Corporation
    Inventors: David Beffroy, Valérie Girardon, Hervé Loury
  • Method of fabricating a polymer part with a negative thermal expansion coefficient and a polymer part obtained by the method
    Publication number: 20030227097
    Abstract: A method of fabricating a polymer part having a negative thermal expansion coefficient includes injecting a thermotropic polymer under controlled temperature and pressure conditions into a mold having an injection inlet substantially equal to the thickness of the part and a length that causes elongation of the polymer.
