  • Low-loss electrode structures using resistive connections for optical modulation applications
    Patent number: 6643048
    Abstract: An optical device includes a grounded base and an optical modulator chip having a top surface, a back surface and side surfaces. The optical modulator chip is positioned on the grounded base with the back surface facing the grounded base. The optical modulator chip includes a first ground electrode, a signal electrode and a second ground electrode located over the top surface of the optical modulator chip. The first and second ground electrodes of the optical modulator chip are interconnected with resistive layers on a surface of the optical modulator chip.
    Type: Grant
    Filed: June 21, 2001
    Date of Patent: November 4, 2003
    Assignee: Codeon Corporation
    Inventors: Ganesh K. Gopalakrishnan, Kevin G. Donovan, Richard C. Blanchard
