Abstract: An optical bus for multi-core processing providing optical data transfer between cores through a single planar waveguide employing a variable-thickness, light-propagation layer having a progressively changing effective refractive index in accordance with lateral position within the light-propagation layer such that light emission from a single light emitter in communication with one core is focused on each of multiple photodetectors in communication with its respective processer core.
