ABSTRACT:
The present invention relates to a method of preparing an optical fiber for optimum coupling with a phototransducer, comprising the following steps: cleaving an end surface on an optical fiber; and depositing a succession of convex lenses on said cleaved surface over the core of the fiber, the lenses being in axial alignment and of decreasing radii of curvature on going away from the fiber. The present invention also provides a system obtained by implementing the method.
