“…The emerging of circuit-level simulators for photonic integrated circuits (PICs) is driven by recent developments in technologies for integration of large-scale monolithic PICs in both, silicon and InP technologies. Arellano et al [3] present their solution for modeling PICs in the framework of the circuit-level simulation tool VPIcomponentMaker TM Photonic Circuits. In their paper The Power of Circuit Simulations for Designing Photonic Integrated Circuits, they demonstrate the combination of different simulation approaches in time domain, frequency domain and time-and-frequency domain (TFDM) for fast and accurate simulations.…”

Welcome to this special issue of the journal Concurrency and Computation: Practice and Experience on Exploiting Silicon Photonics for Energy-Efficient Heterogeneous Parallel Architectures, which contains five original manuscripts that cover a complete range of perspectives.Silicon photonics is undoubtedly expected to play a big role in the evolution in board, crosschip, interposer-level and on-chip interconnection for low-power and/or high-performance computer systems spanning from high-end embedded devices (e.g., tablets and smartphones) and other System-on-Chips (SoCs), up to chips for the High Performance Computing (HPC) domain.The unique features of photonics (e.g., extreme low-latency, end-to-end transmission, high bandwidth density and passive long-range propagation) have the potential constitute a discontinuity element able to modify the expected shape of future computer systems from the design point of view and also from the programmability and/or runtime management perspectives. Summarizing, silicon photonics can bring innovations and benefits into current and foreseeable computing systems directly, due to their intrinsic features, but also indirectly enabling the evolution toward architectures, runtime and resource management approaches that maximize the photonic raw technological opportunities and lead to more efficient overall designs, otherwise impossible.For instance, the extreme low transmission latency (i.e., group velocity of light into silicon, about 15 ps/mm) can potentially allow a higher number of architectural modules to be close each other and thus to enable their effective tight cooperation and communication. However, computer architecture, as well as network on-and off-chip, designs needs to be adapted to extract maximum benefits from the photonic technology, which exposes other substantial differences compared to what designers are well accustomed to. For example, at the moment optical interconnection is end-to-end by nature therefore much of the knowledge and solutions based on store-and-forward paradigm cannot be directly transferred and exploited. However, propagation into a silicon waveguide can occur with limited losses (e.g., even less than 1 dB/cm) over on-chip or interposer distances without signal regeneration needs. In brief, in this arena, new ad-hoc solutions need to be pursued.Then, despite optical communication is very well established and all the involved elements (such as modulators, detectors, waveguides and resonators) have been extensively researched on, silicon photonics applied to computing systems is still in its infancy. Consequently, researchers have already highlighted a deep interaction between design choices at very different layers of abstraction. For this reason, nowadays the whole spectrum of layers, from physical concerns about optical structures on silicon (e.g., module layout and modeling to expose interactions and, for instance, to evaluate and limit insertion losses) up to network issues (e.g., connectivity and topologies, bandwidth and latency) and ev...

“…In particular, the possibility of deriving a NoC-level model that abstracts the functionalities of the PIC without entering into technological details is of paramount importance for accelerating the simulations. An example is given by the libraries and tools for simulations of PIC NoC proposed in [6], [7]. With a fast simulation tool of the NoC, it is possible not only to quickly predict the physical-layer performance and validate the measurements of the NoC but also to optimize the PIC design by assessing the sensitivity to the design parameters.…”
