Abstract: The present invention provides NxN non-blocking switch modules using MMI-based switch elements. The arrangement requires a minimum of control elements to effect switching and uses no crossings of the signal waveguides. The switch control settings may be determined by following a simple and transparent algorithm for the set-up procedure. Very high-order switch fabrics comprising a variety of the taught non-blocking NxN switch modules are envisaged. Determination of the appropriate values for 'N' is a practical consideration which trades-off the performance of the individual switch modules with the complexity required of the associated module interconnection fabric. The spatial switch fabrics that may by built from the non-blocking MMI-based switch arrangements may be combined with both wavelength-division switches and time-division switches to form any combination of higher order space-wavelength-time switch.
