  • Method of positioning and fixing optical fibres in a row of optical fibres and a coupling device provided with such a row of fibres
    Patent number: 5216741
    Abstract: A planar row of optical fibres (9) is obtained by placing the fibres in a mutually parallel position situated contiguously alongside one another. For this purpose, the fibres (9) are placed alongside one another on a substrate (1) in a groove (6) having a laterally somewhat elastic boundary (2, 3) at an accurately determined spacing (D), which is somewhat less than the sum of the diameters of the fibres (9), and then smoothing them and pressing them down so as to be free of crossovers with the aid of a small plate (5) having a thickness D. The spaces left over in the groove (6) are filled with curing filling material. A coupling device for coupling the fibres (9) to corresponding optical channels is obtained by sawing through (along line A--A) and machining the sawn surface obtained.
