“…In a binary, optical communication system, BEP can be defined as the probability that the received photocurrent transmitting 0 is detected above the decision threshold, or it is detected below the threshold while transmitting 1. In the literature related to Wireless NoC [4,19,22] BEP is usually experimentally assessed or estimated by means of analytical formulas for single link, which can be computed based on the estimated value of the received power after the photodiode. However, wireless network design always requires a careful study of cross-link interferences, which may occur among simultaneously links exploiting the same (optical) channel.…”

Networks-on-chip are being regarded as a promising solution to meet the on-going requirement for higher and higher computation capacity. In view of future kilo-cores architectures, electrical wired connections are likely to become inefficient and alternative technologies are being widely investigated. Wireless communications on chip may be therefore leveraged to overcome the bottleneck of physical interconnections. This work deals with wireless networks-on-chip at optical frequencies, which can simplify the network layout and reduce the communication latency, easing the antenna on-chip integration process at the same time. On the other end, optical wireless communication on-chip can be limited by the heavy propagation losses and the possible cross-link interference. Assessment of the optical wireless network in terms of bit error probability and maximum communication range is here investigated through a multi-level approach. Manifold aspects, concurring to the final system performance, are simultaneously taken into account, like the antenna radiation properties, the data-rate of the core-to core communication, the geometrical and electromagnetic layout of the chip and the noise and interference level. Simulations results suggest that communication up to some hundreds of μm can be pursued provided that the antenna design and/or the target data-rate are carefully tailored to the actual layout of the chip.

“…Xu et al [12] proposed a series of solutions to the wavelength drifting problem of microrings and bandwidth loss problem of the optical network, due to PV.

e demand from exascale computing has made the design of high-radix switch chips an attractive and challenging research field in EHPC (exascale high-performance computing). e static power, due to the thermal sensitivity and process variation of the microresonator rings, and the cross talk noise of the optical network become the main bottlenecks of the network's scalability. is paper proposes the analyze model of the trimming power, process variation power, and signal-to-noise ratio (SNR) for the Graphein-based high-radix optical switch networks and uses the extra channels and the redundant rings to decrease the trimming power and the process variation power. e paper also explores the SNR under different configurations. e simulation result shows that when using 8 extra channels in the 64 × 64 crossbar optical network, the trimming power reduces almost 80% and the process variation power decreases 65% by adding 16 redundant rings in the 64 × 64 crossbar optical network. All of these schemes have little influence on the SNR. Meanwhile, the greater channel spacing has great advantages to decrease the static power and increase the SNR of the optical network.

“…Indeed, Wavelength Division Multiplexing (WDM) allows the propagation of multiple signals simultaneously on a same waveguide [5], thus leading to high aggregated bandwidth. However, WDM also leads to interchannel crosstalk noise [6], which negatively impacts the Signal to Noise Ratio (SNR) and, therefore, the Bit Error Rate (BER). The BER to be reached depends on the application requirements and is closely related to the optical devices characteristics: it depends on the photodetector sensitivity [7], on the Microring Resonator transmission spectrum, and on the optical signal power emitted by the laser sources.…”

Optical Network-on-Chip (ONoC) is a promising communication medium for large-scale Multiprocessor System on Chip (MPSoC). Indeed ONoC can outperform classical electrical NoC in terms of energy efficiency and bandwidth density, in particular, because this medium can support multiple transactions at the same time on different wavelengths by using Wavelength Division Multiplexing (WDM). However, multiple signals sharing simultaneously the same part of a waveguide can lead to inter-channel crosstalk noise. This problem impacts the Signal to Noise Ratio (SNR) of the optical signals, which leads to an increase in the Bit Error Rate (BER) at the receiver side. If a specific BER is targeted, an increase of laser power should be necessary to satisfy the SNR. In this context, an important issue is to evaluate the laser power needed to satisfy the various desired communication bandwidths based on the BER performance requirements. In this paper, we propose an off-line approach that concurrently optimizes the laser power scaling and execution time of a global application. A set of different levels of power is introduced for each laser, to ensure that optical signal can be emitted with just-enough power to ensure targeted BER. As result, most promising solutions are highlighted for mapping a defined application onto 16-core ring-based WDM ONoC.
