  • System and method for aligning and attaching optical fibers to optical waveguides, and products obtained thereby
    Patent number: 5926594
    Abstract: An input optical fiber (22), an output optical fiber (24, 26) and a waveguide (14) in an integrated optic chip (IOC) (12) intermediate the fibers are coupled together using service and alignment robots (42; 48, 50, 52). The service robot (42) establishes the three dimensional position of the waveguide. The alignment robots (48, 50, 52) three dimensionally and angularly align the input and output fibers respectively to the input and output legs (16; 18, 20) of the waveguide. An adhesive applying tool (46) coupled with the service robot adheres the input and output fibers respectively to their waveguide input and output legs.
