<p>An optical fibre switch in which a selected one of a number of fibres 11,12 may be introduced into a tapered guide 6 so as to be brought into alignment with a fixed fibre 7 at the narrower end 6.1 of the guide 6, wherein the guide is constituted by a groove 6 in the surface of a substrate 1, the groove 6 being formed by means of a laser. The guide groove 6 may be formed by providing relative movement between the substrate 1 and the laser by means of a micro-precision computer-controlled X Y translator device. <IMAGE></p> |
