Optical Network-on-Chip (ONoC) employs Wavelength Division Multiplexing (WDM) supporting multiple transactions at same time. In this context, many senders and receivers can share the same waveguide to increase the total bandwidth utilization. However, simultaneous transmissions on closed adjacent wavelengths may introduce crosstalk noise through different optical switching elements within the network due to the low wavelength channel spacing and the large Full Width at Half Maximum (FWHM) of the resonance pic of the Microring Res-onator (MR). To address this problem, this paper proposes crosstalk noise aware wavelength allocation in WDM 3D ONoC to improve Signal to Noise Ratio (SNR) performance .
