The present invention is related to a method and device for precision and passive alignment such as precision and passive alignment technology for low cost array fibre access components. A laser carrier is passive aligned to an MT-interface using alignment structures on a replicated carrier. The laser carrier is based on a self-aligned semiconductor laser, flip-chip mounted on a silicon substrate with planar polymeric waveguides. The concept for the alignment according to the invention is shown in figure 1 as a front view of a laser carrier (1) mounted on a polymeric carrier (5).

L'invention concerne un procédé et un dispositif pour l'alignement précis et passif, tel la technique d'alignement précis et passif pour composants d'accès à fibre en réseau de faible coût. Un porteur de laser est aligné passif par rapport à une interface MT au moyen de structures d'alignement sur un porteur répliqué. Le porteur de laser est constitué d'un laser à semi-conducteur auto-aligné, d'une pastille à protubérance montée sur un substrat de silicium à guides d'ondes polymères plans. Le concept d'alignement de l'invention est représenté dans la figure 1, sous la forme d'une vue de face d'un porteur de laser (1) monté sur un porteur polymère (5).
