ABSTRACT:
An optical waveguide reflective star coupler array for interconnecting printed circuit boards or modules in a parallel and broadcast topology. The reflective star coupler array has N reflective star couplers, where N is the number of signal lines to be connected in parallel. Each reflective star coupler has M guide channels, where M is the number of circuit boards to be connected in the backplane configuration. Each guide channel extends between an input port and a mixer. The mixer has a reflective surface arranged so that light propagating along any one of the guide channels is reflected and evenly distributed by the mixer to all of the ports of the star coupler and, hence, to all of the Mth signal lines.
