Patent

CA 2198491

The invention relates to a pigtailing method, i.e., the invention provides an optical device comprising a substrate on which are integrated a layered optical waveguide component (3) and optical fibre ends (13). The optical fibre ends are positioned in grooves (10). The method involves providing a substrate (7) comprising grooves (10), notably V-shaped grooves, with a separately made optical waveguide component (3). The component (3) is made on a separate flat substrate (1) and released by virtue of a releasable layer (2) present on the flat substrate (1). An advantageous releasable layer is made of a water- soluble salt. The invention also pertains to flexible waveguide sheets (3) such as can be used in the above method or, if provided with waveguide channels (12), as flexible waveguide components themselves.

L'invention concerne un procédé de raccordement à queue de cochon, et notamment un dispositif optique comprenant un substrat sur lequel on a intégré un composant (3) de guide d'onde optique à couches ainsi que des extrémités (13) de fibres optiques, lesquelles sont disposées dans des rainures (10). Ce procédé consiste à pourvoir un substrat (7) comprenant des rainures (10), notamment des rainures en forme de V, d'un composant (3) de guide d'onde optique autonome, fabriqué sur un substrat plat (1) séparé et détaché de celui-ci à l'aide d'une couche (2) libératrice présente sur ledit substrat (1) et avantageusement composée d'un sel soluble dans l'eau. L'invention se rapporte également à des feuilles de guide d'onde flexibles telles (3) que l'on puisse les utiliser dans le procédé ci-dessus, ou à des feuilles qui, lorsqu'elles sont pourvues de canaux (12) de guide d'onde, servent elles-mêmes de composant de guide d'onde flexible.
