  • Cascaded fiber fabry-perot filters
    Patent number: 6985235
    Abstract: The invention relates to Fabry-Perot interferometers (FFPI) comprising two or more optically coupled tunable all-fiber Fabry-Perot component filters, wherein the Fabry-Perot cavity of the filter is formed within a bare section of optical fiber held within a fiber ferrule. The wavelength transmitted by the interferometer can be tuned thermally or electromechanically for a fiber containing the Fabry-Perot cavity bonded into a groove of a metal substrate. The interferometer can be tuned by changing the length of Fabry-Perot cavity, including by the use of a piezoelectric transducer.

  • Cascaded fiber fabry-perot filters
    Publication number: 20030076505
    Abstract: The invention relates to Fabry-Perot interferometers (FFPI) that are thermally or electromechanically tunable. These interferometers are particularly useful as components of optical filters which can be tuned by coordinated tuning of the component filters. The tunble FFPI of this invention can be made by fiber bonding or fusion techniques and as a result, are relatively low cost devices.
