Abstract
A photonic array bus provides a connectorless, computer backplane-like communication systems for advanced data processing and communications systems requiring operation rates exceeding 1 gigahertz. Components of a multiple component advanced data processing or communications system are coupled to pairs of laser transmitters and laser receivers. The laser transmitter and receiver pairs are arrayed in a coplanar circular fashion about a central disperser lens. A laser transmitter emits a laser beam incident on the central disperser lens. The central disperser lens disperses the laser beam into a coplanar array of laser beams illuminating the laser receivers. Multiple channel operation is achieved by 'stacking' along the length of the disperser lens coplanar arrays of pairs of laser transmitters and receivers.
