Abstract
Photonic network-on-chip (PNoC) architectures employ photonic waveguides with dense-wavelength-division-multiplexing (DWDM) for signal traversal and microring resonators (MRs) for on-off-keying (OOK) based signal modulation, to enable high bandwidth on-chip transfers. Unfortunately, the use of larger number of DWDM wavelengths to achieve higher bandwidth requires sophisticated and costly laser sources along with extra photonic hardware, which adds extra noise and increases the power and area consumption of PNoCs. This paper presents a novel method (called 4-PAM-P) of generating four-amplitude-level optical signals in PNoCs, which doubles the aggregate bandwidth without increasing utilized wavelengths, photonic hardware, and incurred noise, thereby reducing the bit-error-rate (BER), area, and energy consumption of PNoCs. Our experimental analysis shows that our 4-PAM-P signaling method achieves equal bandwidth with 4.2× better BER, 19.5% lower power, 16.3% lower energy-per-bit, and 5.6% less photonic area compared to the best known 4- amplitude-level optical signaling method from prior work.
