1. An optical cross connect apparatus, comprising:

  • a first planar layer comprising m optical paths formed on oppositely disposed surfaces of the first planar layer;

    a second planar layer comprising n optical paths formed on oppositely disposed surfaces of the second planar layer; and

    an optical switch array comprising a plurality of optical switches, wherein the optical switches permit optically coupling any optical path of the first planar layer with any optical path of the second planar layer, and control signals communicate to the optical switches to change the optical switches between a transparent state that permits signal transmission and an opaque state that prevents signal transmission.
