Abstract
An arrangement to optically couple multiple waveguides to a few-mode fiber comprises an optical assembly to respectively deflect light beams impacting the optical assembly and an optical coupler being configured to convert a respective fundamental mode of a plurality of the light beams coupled out of a respective different one of a plurality of the multiple waveguides and impacting the optical coupler to a respective higher order mode of each of the plurality of the light beams. The optical assembly comprises a first optical device to deflect each of the light beams impacting the first optical device from the optical coupler to a core section of the few-mode fiber to transfer light within the few-mode fiber.
