Abstract
An electronics system communicates among its subsystems by a free-space optical bus. The bus transmits signals bidirectionally along a single linear axis as polarized beams of light. Each subsystem has a bus interface unit for generating outgoing beams along both axial directions, and for receiving incoming beams from both axial directions. The interface units use laser generators, photodetectors, and amplitude beam splitters.
