Abstract: The invention is a method and apparatus for creating mode division multiplexed channels capable of integration into photonic integrated circuits with direct spatial separation at the receiver end, thus removing the need for a DMUX module or at least significantly simplifying it. This is achieved by using a set of actuators that induce controllable mode mixing in a multi-mode fiber (MMF) at the transmitter in such a way that spatially separated channels are achieved at the receiver. As a result, no DMUX is required and failure of a single channel does not cause total communication link failure as occurs in links implemented with MUX/DMUX.
