  • Enhancing fiber-optic sensing technique using a dual-core fiber
    Patent number: 7236673
    Abstract: An optical fiber for use in fiber optic sensing of a test sample includes a first core and a second core. The second core is generally coaxially disposed within the first core and is sized smaller than the first core. The second core is capable of delivering pulsed laser energy from the laser for nonlinear optical excitation of the test sample. Nonlinear optical feedback signals can then be collected in both the first core and second core for improved detection efficiency relative to conventional single-mode and multi-mode fibers.
    Type: Grant
    Filed: March 9, 2006
    Date of Patent: June 26, 2007
    Assignee: The Regents of the University of Michigan
    Inventors: Jing Yong Ye, Theodore Norris, James R. Baker, Jr., Thomas Thommey, Mon Myaing
