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.

Method and device for optical switching and variable optical attenuation

A mode conversion apparatus including a dynamic waveguide section associated with a plurality of control elements that, when activated, are able to produce a periodic refractive-index perturbation pattern in the dynamic waveguide section, wherein the periodic refractive-index perturbation pattern is able to convert at least a fraction of an input signal from a first guided mode of the dynamic waveguide section into a second guided mode of the dynamic waveguide section.
