  • Method of making a Mach-Zehnder interferometer, and related device
    Patent number: 6862386
    Abstract: A method of making an all-fiber Mach-Zehnder interferometer comprising at least two optical fibers comprises the steps of bringing the fibers in a reciprocal contact relationship for a contact section thereof; fusing together and tapering the fibers in at least a first portion of said contact section; forming at least two optical couplers between the fibers in a second and a third portions of said contact section, located at opposite sides of said first portion.
    Type: Grant
    Filed: March 28, 2002
    Date of Patent: March 1, 2005
    Assignee: Corning Incorporated
    Inventors: Valeria Corio, Aurelio Pianciola
  • Method for producing an optical coupler for extracting a signal from a polarization maintaining optical fiber, and corresponding coupler
    Patent number: 6701046
    Abstract: A fused optical coupler comprising a polarization maintaining fiber and a standard fiber is provided. The cross-section of the said standard fiber is smaller than the cross-section of the polarization maintaining fiber in the area of fusion of the coupler. The internal forces in the coupling area are sufficiently low to provide an extinction ratio of more than 20 dB at the output of the polarization maintaining fiber.
