<p>The invention relates to a method and an apparatus for manufacturing an optical coupling arrangement, and a specific coupling arrangement. A substrate waveguide (306) and at least one coupling element (304, 306) in the coupling arrangement are made of polymer material in the same replication process at the same time. At least one diffractive coupling element (304, 306) is then formed in the polymer material by placing the polymer material against a replication mould, which comprises a surface profile model of at least one diffractive coupling element (304, 306) that is patterned into the replication mould by means of micro lithography.</p> |
