1. An optical system, comprising:
(i) multiple input optical fibers;
(ii) an optical mode multiplexer/demultiplexer coupled to said input optical fibers said optical mode multiplexer/demultiplexer comprising a plurality of metamaterial structures having length l and forming at least one stage of metamaterials having a length L and a width W, and
a. the at least one stage of metamaterials is being situated on a surface of the optical mode multiplexer/demultiplexer facing the input optical fibers, and the length L of the at least one stage of metamaterials is oriented at angles between 60 and 120 degrees relative to the axis of the input fibers; and
b. the metasurfaces are structured to receive a first optical signal having a first mode from at least one of said multiple input optical fibers and convert the first mode to a different mode.
