A method, apparatus, and system in which a network system includes a virtual graph composed of a plurality individual networks. In some embodiments, the device may include a helical coil having a contracted state, adapted for radial expansion and longitudinal contraction to an expanded state. The middle panel has opposing first and second surfaces defining a corrugated profile having a plurality of bonding surfaces, the bonding surfaces being attached to the first and second interface surfaces to thereby define a plurality of laterally oriented channels. The waveguide is configured to emit a first portion of the light above the rear surface for reflection by the surface of the substrate back into the waveguide and through the front surface of the waveguide, and to emit a second portion of the light through the front surface.
