1. A method for manufacturing an optical coupling arrangement comprising a substrate waveguide and at least one coupling element for coupling optical radiation between the substrate waveguide and the environment, the method comprising:

  • making both the substrate waveguide and at least one diffractive coupling element of polymer material at a same time in one replication process, the process comprisingforming both the substrate waveguide and at least one diffractive coupling element of the polymer material by placing the polymer material against a replication mould comprising a surface profile model of at least one diffractive coupling element that is patterned into the replication mould by means of micro lithography.
