  • Broadband matching network for an electroabsorption optical modulator
    Patent number: 6677830
    Abstract: A broadband impedance matching circuit for use with an optical device such as an electroabsorption optical modulator comprises a microstrip transmission line, including pairs of like-sized open stubs disposed on opposite sides of the transmission line along its length. The number of open stubs, as well as their dimensions and location are chosen to provide for broadband impedance matching (from dc to several GHz) between an external electrical signal source and the optical device.
    Type: Grant
    Filed: September 11, 2001
    Date of Patent: January 13, 2004
    Assignee: TriQuint Technology Holding Co.
