  • Device for coupling a light source to an optical fiber
    Patent number: 4030811
    Abstract: A device for coupling a light source, in particular a semiconductor laser, to an optical fiber in which the light source and the optical fiber are each connected to a cylindrical or part-cylindrical support and a coupling member is provided having two V-shaped grooves enclosing mutually a substantially right angle, in which the cylindrical supports, possibly carried by an additional member, after their mutual adjustment in the V-shaped grooves, are secured to the contact member. One of the supports may advantageously be provided in a V-shaped groove of a cylindrical or part-cylindrical auxiliary member which is secured in one of the V-shaped grooves of the coupling member.

  • Method of coupling light conductors
    Patent number: 4030810
    Abstract: A connecting plug for coupling light conductors using a coupling liquid and a method of coupling light conductors by sucking the conductors into the plug.A transverse duct opens into a capillary duct in the plug. A coupling liquid is forced into the capillary from the transverse duct. The glass fibres are then inserted as far as into the liquid, and are subsequently sucked further into the capillary by sucking off the liquid through the transverse duct.
