  • Dual-parameter optical waveguide grating sensing device and sensor
    Patent number: 6833541
    Abstract: In the present invention an optical waveguide grating sensing device for a dual-parameter optical waveguide grating sensor includes a first optical waveguide grating of a first resonant wavelength provided in a first section of an optical waveguide and a second optical waveguide grating of a second resonant wavelength provided in a second of an optical waveguide. The first and second gratings have different coefficients of rate of change of wavelength as a function of temperature and have substantially the same coefficient of rate of change of wavelength as a function of stain.
    Type: Grant
    Filed: September 17, 2002
    Date of Patent: December 21, 2004
    Assignee: Aston Photonic Technologies Ltd.
    Inventors: Xuewen Shu, Yu Liu, Donghui Zhao, Lin Zhang, Ian Bennion, Bashir Aliyu Labbo Gwandu, Filip Floreani
