Abstract
The invention relates to an optical coupler () in a vertical configuration, capable of working for a wavelength and comprising a first waveguide () and a second waveguide (). The second waveguide () has a patterning () in the form of a series of patterns (), the patterns () extending along a transverse direction (X) perpendicular to the longitudinal direction (Z), being parallel to each other and orthogonal to the general direction of the first waveguide (), each pattern () being arranged both in the core () and the cladding () of the second waveguide () and having parameters influencing the evanescent wave coupling between the first waveguide () and the second waveguide (), said parameters being chosen such that the coupling (C) is greater than 15%.
