  • Method and apparatus for on-wafer testing of an individual optical chip
    Patent number: 6925238
    Abstract: A method for testing an optical chip, while the optical chip is still on a wafer, utilizing an optical probe, includes the steps of creating an access point on the wafer adjacent the optical chip. The optical chip having a waveguide having an axis. A portion of the waveguide is removed to form the access point such that light exiting the planar optical waveguide is directed in a direction substantially different from the axis of the waveguide. An optical probe is placed along a propagation path of the exiting light to optically couple the optical probe and optical chip.
