| http://www.w3.org/ns/prov#value | - An MMI coupler device comprises a multi-mode slab waveguide, which can support several modes, with N inputs (in the case here including demultiplexing only one input is needed) and M outputs and is based upon a self-imaging property wherein an input field profile is reproduced in a single or multiple images at periodic intervals along the propagation direction of the slab waveguide.
