Ring versus bus: A BER comparison of photonic integrated networks-on-chip

Abstract

Silicon-photonics bus and ring networks-on-chip are evaluated in terms of transfer function and bit error rates at 10Gb/s, demonstrating that the ring architecture can be effectively used with physical layer performance similar to the bus. © 2015 IEEE

BER evaluation of a low-crosstalk silicon integrated multi-microring network-on-chip

“…The fabricated PIC is a proof of concept of the proposed MMR architecture. This paper aims to experimentally validate such proof of concept and extends the results in [14,15] derived for transmissions on a single wavelength. More specifically, the experimental characterization of the integrated Si-based MMR NoC are reported in terms of both transmission spectra and bit error rate (BER) measured for single-wavelength and multiplewavelength concurrent transmissions at 10 Gb/s.…”

Ring Versus Bus: A Theoretical and Experimental Comparison of Photonic Integrated NoC

“…Both comparisons are carried out considering the worst case scenario from the performance point of view, occurring when concurrent transmissions take place at the same wavelength leading to homo-wavelength crosstalk [19]- [21]. The results extend the initial works in [22], [23] focusing on a single topology (i.e., ring), and in [24] limited to an experimental comparison, enabling the validation of the theoretical framework. The theoretical results provide also insights on the best NoC topology and the experimental results confirm that PIC technology is a viable solution for supporting concurrent transmissions on the same wavelength.…”
