  • Planar waveguide devices and fiber attachment
    Patent number: 6377732
    Abstract: According to the present invention, an optical waveguide is provided on a silica or silicon substrate using MPACVD and ICP etching processes. Optical fiber is coupled to the waveguide by positioning the fiber in a groove formed in the waveguide and compressing a top lid on the fiber. The top lid is secured to the waveguide and fiber by an epoxy or a solder. In a solder based embodiment, the cladding of the fiber may have a metallization evaporated thereon.
