Title (EN) DIRECT LASER WRITING AND CHEMICAL ETCHING AND OPTICAL DEVICES
(FR) ÉCRITURE LASER DIRECTE ET GRAVURE CHIMIQUE, ET DISPOSITIFS OPTIQUES
Abstract:
(EN) This invention concerns an optical device comprising a unitary substrate of optically transparent material. The unitary substrate has formed therein at least one collection lens (104a to 104f) and channel (106a to 106f), the channel (106a to 106f) for receiving an optical fibre and arranged to align the optical fibre inserted therein such that the collection lens couples light collected by the collection lens (104a to 104f) into the optical fibre.
(FR) La présente invention se rapporte à un dispositif optique qui comprend un substrat unitaire en matériau optiquement transparent. Au moins une lentille de collecte (104a à 104f) et au minimum un canal (106a à 106f) sont formés à l'intérieur du substrat unitaire, le canal (106a à 106f) permettant de recevoir une fibre optique et étant conçu pour aligner la fibre optique introduite à l'intérieur de ce canal de telle sorte que la lentille de collecte couple la lumière collectée par ladite lentille de collecte (104a à 104f) dans la fibre optique.
