Optical coupler for a multicore fiber

An optical coupler for optically coupling a multicore fiber having a plurality of optical cores to a plurality of individual fibers, the optical coupler comprising:

• a support in which the multicore fiber is embedded in a defined alignment and a first group of the optical cores is oriented along a first line and a second group of the optical cores is oriented along a second line, said support having an end face;
• support elements including a planar first support element to which a first group of the individual fibers can be connected and a second planar support element to which a second group of the individual fibers can be connected, each of said support elements having surfaces;
• and
• waveguides inserted into said surfaces of said support elements, a respective one of said support elements is directly attached, by a connection side, to said end face of said support, such that the optical cores of the first group of the multicore fiber are in alignment with said waveguides of said planar first support element, and the optical cores of the second group are in alignment with said waveguides of said planar second support element, and the first and second lines of the first and second groups of the optical cores and, corresponding thereto, said surfaces of said support elements, are disposed at an angle in relation to each other.
