A method of mode selective coupling or mode multiplexing between integrated multimode () and single mode () waveguides. Evanescent coupling and tapering is used so that the signal may be transferred adiabatically from a first region of a first waveguide to a second, proximal, region of a second waveguide.

Method and apparatus for optical mode division multiplexing and demultiplexing

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.
