  • Variable optical attenuator with polarization maintaining fiber
    Patent number: 6611649
    Abstract: An electrically controllable, variable optical attenuator (VOA) is disclosed, in which polarization maintaining fiber is employed. The fiber is modified to expose the evanescent field of optical energy transmitted therein, by removing material therefrom in a direction parallel to either the fast or slow axis of the fiber, while preserving the polarization maintaining property of the fiber. A controllable material is formed over the modified portion, to remove optical energy in response to a changeable stimulus applied, which changes the refractive index of the material. Related packaging, material composition and system aspects of the attenuator are also disclosed.
    Type: Grant
    Filed: March 19, 2001
    Date of Patent: August 26, 2003
    Assignee: Molecular OptoElectronics Corporation
    Inventors: Kwok Pong Chan, Kim Roger LaBarge
