Definitions

  • a sending/receiving element may be either a fiber, a lens, a collimator, or a combination of these.
  • collimation of signals effectively "straightens out" the vectors of the waves of an optical signal 5 as they leave a fiber. This can be accomplished by passing the signals through a lens 6. Once the signals are passed through the lens and collimated, the signal vectors may be effectively coupled between two fibers across free space.
  • focal point is used here to describe the aplanatic patch upon a focal plane 10 which desirably intersects with the face of a fiber 11, the focal plane 10 being at a given focal length 7 of the lens.
  • the focal plane 10 is that plane through which the lens 8 may focus depending upon the location of a light source 12 relative to the lens 8.
  • the focal point 9 In order to effectively collimate a signal from a fiber 13, the focal point 9 must be positioned very near or at the end of the fiber face 11, and be optically aligned with the center axis of the fiber face 11. Further, to properly position the focal point 9, the lens must be positioned at a particular focal length 7 from the fiber face 11. If the fiber face 11 is not properly positioned with respect to the focal point 9, the optical signal will not be efficiently collimated, resulting in significant signal loss.
  • the focal point is located in the center and flush with a flat end of a GRIN lens.
  • a GRIN lens the focal point of the GRTN lens is not always accurate (i.e. the focal point may not be located at the end of the GRIN lens and thus not on the fiber face even when the face is butted up to the GRTN lens).
  • GRTN lenses as in prior approaches present problems with mating the desirable angle polished face of a fiber with the flat portion of the GRTN lens.
  • a further problem with collimator units built as individual units is practical placement in, for example, fiber optic switches.
  • the individual lens/fiber units are positioned by hand and glued in place.
  • any movement by the fiber may move the lens.
  • the fiber face may move relative to the lens focal point if the fiber itself is moved.

Ce dispositif de collimation comprend une lentille pourvue d'une partie de montage, cette lentille présentant une longueur focale, un dispositif de fixation comportant une face et pouvant loger et positionner une fibre optique de telle sorte qu'une face de la fibre optique soit sensiblement alignée avec la face du dispositif de fixation, et un élément d'espacement adjacent à la face de la partie de fixation et de la partie de montage de la lentille, cet élément d'espacement maintenant une distance de séparation entre le dispositif de fixation et la ou les lentille(s). Dans au moins un mode de réalisation, le procédé selon l'invention comprend un procédé de réalisation d'un dispositif de collimation servant à collimater un signal optique, ce procédé consistant à se munir d'un dispositif de fixation pourvu d'une face, ce dispositif de fixation pouvant loger une fibre et positionner la face de cette fibre, à se munir d'au moins une lentille et à connecter le dispositif de fixation à la lentille ou aux lentilles de telle sorte que les paramètres de lentille par rapport à la longueur focale soient dissociés de la position de la face de la fibre. Ce procédé peut également comprendre la fabrication de réseaux de lentilles destinés à un collimateur, lequel consiste à fabriquer une plaque de lentilles, cette plaque comprenant un côté de montage et des lentilles, à lier une plaquette de matériau d'espacement au côté de montage de la plaquette de lentilles ainsi fabriquée, ce matériau d'espacement comprenant une face dorsale, et à découper la plaquette de lentilles et la plaquette de matériau d'espacement en réseaux lenticulaires individuels.
