  • Method to construct optical infrastructure on a wafer
    Patent number: 6738538
    Abstract: This invention discloses a novel method of manufacturing optical communications infrastructures that are implemented on a flat semiconductor wafer. This invention has the following characteristics which enable the efficient manufacturing of a combination of elements onto such a wafer: the inherent surface flatness, crystal purity and uniformity over a relatively large dimension for semiconductor wafers; the low cost and wide availability of such wafers; and the ability to combine several types of elements onto the wafer, on a very dense scale, and in a highly repeatable and mechanically aligned manner.
    Type: Grant
    Filed: October 25, 2001
    Date of Patent: May 18, 2004
    Inventors: Patrick R. Antaki, Mark N. Shepard
