PCT No. PCT/EP95/03245 Sec. 371 Date Jul. 2, 1997 Sec. 102(e) Date Jul. 2, 1997 PCT Filed Aug. 16, 1995 PCT Pub. No. WO96/07116 PCT Pub. Date Mar. 7, 1996An optical device is provided by a pigtailing method and comprises a substrate on which are integrated a layered optical waveguide component and optical fibre ends. The optical fibre ends are positioned in grooves). The method involves providing a substrate comprising grooves, notably V-shaped grooves, with a separately made optical waveguide component. The component is made on a separate flat substrate and released by virtue of a releasable layer present on the flat substrate. An advantageous releasable layer is made of a water-soluble salt. Flexible waveguide sheets such as can be used in the previously described method or, if provided with waveguide channels, as flexible waveguide components themselves are also disclosed.
