An optimized low-power optical memory access network is proposed to alleviate the cost of microring resonators (MRs) in kilocore systems, such as the pass-by loss and integration difficulty. Compared with traditional electronic bus interconnect, the proposed network reduces power consumption and latency by 80% to 89% and 21% to 24%. Moreover, the new network decreases the number of MRs by 90.6% without an increase in power consumption and latency when making a comparison with Optical Ring Network-on-Chip (ORNoC).

With the application of optical add-drop multiplexers, wavelength assignment has become an important issue in SONET/WDM design. Among wavelength assignment methods, circle construction is of great importance. In this paper, we propose a novel matrix based circle construction algorithm for all-to-all uniform traffic in a bidirectional SONET/WDM ring.
