  • Optical fiber thermal compensation device
    Patent number: 6944374
    Abstract: An optical filter having at least one optical fiber component and a thermal compensation device which includes a first, second and third member in which the thermal compensation device has a first and a second fixing point, the first, second and third members are made from materials having first, second and third thermal expansion coefficients, the optical fiber component is attached to the thermal compensation device at the first and the second fixing points thus defining a composite thermal expansion. The optical filter is such that the composite thermal expansion compensates for thermal behavior of the optical fiber component.
    Type: Grant
