Abstract :
Photonic Network-on-chip (PNoC) is a promising alternative to design low-power and high-bandwidth interconnection infrastructure for multicore chips. The micro ring resonators, which are essential building blocks for designing PNoCs are susceptible to crosstalk that can notably degrade signal-to-noise ratio (SNR), reducing reliability of PNoCs. This paper proposes two novel encoding mechanisms to improve worst-case SNR by reducing crosstalk noise in microring resonators used within high-radix and low-diameter crossbar-based PNoCs.
