The ability to efficiently connect many high-speed ports or "smart" pixels is of critical importance for large-capacity communications. High bandwidth, 2-D optical planes can be used to achieve such an interconnection and avoid eventual electronic bottlenecks. However, existing solutions do not efficiently resolve a situation in which one plane is required to simultaneously and reconfigurably communicate with many subsequent planes. One previous solution involves etching large holes in each plane's substrate establishing only a predetermined static configuration between any two planes.
