Hybrid photonic-plasmonic electro-optic modulator for optical ring network-on-chip
摘要： One of the most essential components in an optical network-on-chip (ONoC) is the electro-optic modulator. Mach-Zehnder and micro-ring resonator electro-optic modulators are widely used in ONoC, and conventional silicon-based modulators have large footprints and low modulation rates and lack thermal stability. In this paper, a new electro-optic modulator based on surface plasmon polariton (SPP) is proposed, and indium tin oxide (ITO) is utilized as a conducting transparent oxide (TCO) material in the electro-optic modulator. The modulated optical signal is suitable for ONoC with architectures such as optical ring network-on-chip (ORNoC). When the wavelength is 1550 nm, the average coupling efficiency is over 70%, the extinction ratio of the electro-optic modulator is -14.1 dB, and the insertion loss is 2.1 dB. In addition, the size of the modulator is less than 8.50 μm×1.6 μm, and the modulation operating bandwidth is up to 0.7171 Tbit/S. When the wave division multiplex (WDM) mode is used, the operating bandwidth is up to 2.1 Tbit/S, and the energy consumption per bit (E) is 5.7211 fJ/bit. All of the above results were obtained from 3D-FDTD Simulation Software and MATLAB.

摘要： Energy ef?ciency of an optical network-on-chip (ONoC) largely relies on an effective laser power management strategy. Addressing the limitations of existing techniques, we propose a Task Mapping-Assisted Laser Power Scaling (TMALPS) framework to optimize the energy consumption and the application execution time of an ONoC. Through the combination of task mapping exploration and runtime laser power recon?guration applied to a wide range of application benchmarks, our TMALPS framework achieves an average of 66% saving of the energy-delay product, compared to a baseline scenario where the optimization techniques are not applied. Signi?cant improvement over existing techniques was also observed. The hardware overhead required to support our TMALPS framework is minimal with intelligent reuse of existing on-chip hardware resource.

[IEEE 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Huangshan, China (2019.8.5-2019.8.8)] 2019 18th International Conference on Optical Communications and Networks (ICOCN) - A Traffic-Balanced and Thermal-Fault Tolerant Routing Algorithm for Optical Network-on-Chip
摘要： How to make efficient data routing is one of the key points in optical network-on-chip. Traditional routing algorithms solve deadlocks by prohibiting turns. However, it cannot provide uniform adaptiveness in optical network-on-chip, which results in unbalanced traffic as well as thermal-faulty nodes and thereby degrades the network performance. To achieve traffic balancing and thermal-fault tolerant, a traffic-balanced and thermal-fault tolerant routing algorithm (TBTFTA) is proposed in this paper which considers traffic and temperature information simultaneously. TBTFTA can handle the congestion and different types of thermal-faulty nodes by a distributed path selection strategy. Simulation based on OPNET is carried out to evaluate the proposed algorithm. The results show a lower latency and an improved throughput by 37.39%, 43.62%, and 49.32% compared with the traditional algorithm under various traffic patterns.

Low-power optical network-on-chip using low-loss multilayer silicon wire waveguide
摘要： Photonic network-on-chip can benefit the future integrated structures only if it consumes less power. The optical devices used in the network router such as waveguides and switches must be low power to make the overall network power efficient. In this paper, a passive 4 × 4 optical network-on-chip router has been designed employing wavelength-division multiplexing using a novel multilayer silicon wire waveguide. The switching device, serially coupled double-ring resonator for the router, is also based on this waveguide. The designed router is first of its kind that comprises a multilayer silicon photonic wire waveguide and an improvised waveguide-based ring resonator switch. The performance evaluation of designed on-chip optical network router has been carried out in terms of bit error rate (BER). It has been shown that the designed optical network router offers low losses and better BER performance due to its novel low-loss devices and structure. Additionally, the designed network is complementary MOS compatible and non-blocking, i.e., all processing cores can transmit data to each other on all available wavelengths without any conflict.

New Path-Setup Method for Optical Network-on-Chip
摘要： With high bandwidth, low interference, and low power consumption, optical network-on-chip (ONoC) has emerged as a highly efficient interconnection for the future generation of multicore system on chips. In this paper, we propose a new path-setup method for ONoC to mitigate contentions, such as packets, by recycling the setup packet halfway to the destination. A new, strictly non-blocking 6 × 6 optical router is designed to support the new method. The simulation results show the new path-setup method increases the throughput by 52.03%, 41.94%, and 36.47% under uniform, hotspot-I, and hotspot-II traffic patterns, respectively. The end-to-end delay performance is also improved.
