<p>The present document relates to an optical coupling device. In particular, the present document relates to an optical coupling device which is adapted to couple light between a plurality of single-mode fibers and a plurality of cores of a multi-core fiber. An optical coupling device (200) adapted to couple light between a light source and/or drain (204) and a corresponding core of a multi-core fiber (205) is described. The core of the multi-core fiber (205) is positioned at a lateral core distance (x) greater zero from a center axis of the multi-core fiber (205). The coupling device (200) comprises a first interface, at a first side of the coupling device (200), adapted to connect with the multi-core fiber (205); a second interface, at the first side of the coupling device (200) and adjacent to the first interface, the second interface being adapted to connect with the light source and/or drain (204), respectively; and position the light source and/or drain (204) at a lateral axis distance (d) greater zero from the center axis of the multi-core fiber (205). The coupling device (200) comprises a lens array (201) having an outer lens (211) and an adjacent center lens (212), wherein the outer lens (211) is adapted to collimate light from the light source (204) and/or focus light to the light drain (204); and wherein the center lens (212) is adapted to collimate light from the center axis of the multi-core fiber (205) and/or focus light to the center axis of the multi-core fiber (205); and a reflective device (203), spaced from the lens array (201) opposite of the first side of the coupling device (200), adapted to reflect light coming from the outer lens (211) towards the center lens (212) and/or to reflect light coming from the center lens (212) towards the outer lens (211).</p> |
