Abstract:
1. An arbitration system comprising: a loop waveguide; a power waveguide optically coupled to a source that injects unmodulated channels of light into the power waveguide, each channel corresponding to a cluster; microrings disposed between and adjacent to the power waveguide and the loop waveguide, each microring in the set configured to have resonance with one of the channels and evanescently couple the channel from the power waveguide into the loop waveguide; and interior microring groups, each microring group having a number of microrings disposed adjacent to the loop waveguide and electronically coupled to a cluster, such that each microring in a group is configured to extract a channel propagating in the loop waveguide when selectively activated and send an electrical signal to the electronically coupled cluster.
