An optical switching device for switching M input signals into N output signals, wherein M and N are each equal to or greater than one, including a mode division multiplexer to join the M input signals into a first multi-mode signal having M initial modes, a mode converter to convert the first multi-mode signal into a second multi-mode signal having N converted modes, and a mode division demultiplexer to separate the second multi-mode signal into the N output signals, wherein the converter is able to be controllably activated such that the N converted modes are separated by the demultiplexer to the N output signals according to a desired scheme.
