  • Publication number: 20050018974
    Abstract: A method and apparatus is disclosed for enabling a coupling of at least one optical fiber with an optoelectronic device. The apparatus comprises at least one v-groove for receiving at least one optical fiber. A first end of the apparatus is then polished at a predetermined angle in order to enable an optical coupling with the optoelectronic device.

  • Publication number: 20050018993
    Abstract: A method and apparatus is disclosed for creating an optical ferrule. A mechanical coupling of the ferrule is achieved, at a first end of the ferrule, using at least two dowels while an optical coupling of the ferrule with an optical device is achieved, at a second end of the ferrule, using a total internal reflection.
