A modular photonic interconnection network based on a combination of basic 2x2 all-optical nodes is presented. The proposed architecture is synchronous, can operate up to 160Gb/s and exhibits self-routing capability and very low switching latency. 1. Introduction In the field of high-performance computing systems, current electronic interconnection networks(More)
—Enhanced-SSFM digital backpropagation (DBP) is experimentally demonstrated and compared to conventional DBP. A 112 Gb/s PM-QPSK signal is transmitted over a 3200 km dispersion-unmanaged link. The intradyne coherent receiver includes single-step digital backpropagation based on the enhanced-SSFM algorithm. In comparison, conventional DBP requires twenty(More)
—In flexi-grid optical networks, effective defragmenta-tion (i.e., re-optimization) solutions are required to efficiently exploit network spectrum resources. However, current defragmen-tation solutions can only be implemented thanks to the presence of additional resources, such as spare extensive transponders. In this study, focusing on optically-amplified(More)
Abnormally synchronized neural oscillations within the subthalamic nucleus have been proposed as a contributor to the pathophysiology of Parkinson's disease. Recent studies have demonstrated phase-amplitude coupling between beta rhythms and high frequency oscillations in the subthalamic nucleus in unmedicated Parkinsonian patients. However, the nature of(More)
We present the design and experimental evaluation of an Optical Multicast System for Data Center Networks, a hardware-software system architecture that uniquely integrates passive optical splitters in a hybrid network architecture for faster and simpler delivery of multicast traffic flows. An application-driven control plane manages the integrated optical(More)
