摘要:

Low-loss, non-blocking, scalable passive optical interconnect network on-lhip ( LOOKNoC) structure was proposed based on 2 *2 optical exchange switches, using wavelength division multiplexing (WDM) technology to expand to 8 *8, 16 *16, 32 *32, 64 *64 passive optical interconnection networks, which can achieve non-blocking communication. The experimental results show that based on the 16 *16 optical interconnection network structure, the number of microring resonators (MRs) in LOOKNoC was reduced by 90.9%, 90.9%, 20.0% and 75.0% compared with the generic wavelength-routed optical router (GWOR), λ-router topology and CrossBar structure. By testing the performance parameters based on the structure of 16 *16 by the OMNET + + platform, as the result shows, the average insertion loss of LOOKNoC is 3.0%, 11.6%, 4.8% and 16.7% less than that of

GWOR, λ-router, Mesh, and CrossBar structures.
