Abstract

An optical coupling device including, in sequence, a focusing lens and an optical coupling network, the coupling device being symmetric with respect to a plane, the focusing lens formed in a core layer, as a front face, perpendicular to the plane, the optical coupling network including a plurality of trenches, formed on the front face, and convex in shape, the optical coupling network including, in sequence, a first sub-network and a contiguous second sub-network, respectively delimited, by a first contour and a second contour, the first and second contours extending in a divergent manner and convergent manner respectively.
