Abstract
Various embodiments of the present invention relate to systems and methods for achieving low-latency, prioritized, distributed optical-base arbitration. In one embodiment, an optical arbitration system (100,1100) comprises a waveguide (102,1102) having a first end and a second end, and a source (104,1104) optically coupled to the first end of the waveguide and configured to input at least one wavelength of light into the waveguide. The system also includes a number of wavelength selective elements (106-109,1106-1109) optically coupled to the waveguide. Each wavelength selective element is capable of extracting a wavelength of light from the waveguide when activated by an electronically coupled node. An arbiter (110,116,120,1112,1116,1120) is optically coupled to the second end of the waveguide and to the waveguide between the source and a wavelength selective element located closest to the source along the waveguide.
