Demonstration of continuous multiple access with image-rejection coherent receiver and DML transmitters
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Restricted access - publisher's policyWe demonstrate a UD-WDM PON using DML transmitters with multilevel intensity modulation, both in base-band and RF, and a spectrally-efficient heterodyne receiver. We provide comparison with a homodyne receiver. Two users ... -
Distributed and autonomous flow routing based on deep reinforcement learning
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessA DRL approach with a specific reward function is proposed for autonomous flow routing operating on multilayer scenarios. Illustrative results reveal that the DRL achieves optimal flow routing in terms of cost and service ... -
Data plane technology-agnostic control and orchestration architecture for optical disaggregated data centers
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Restricted access - publisher's policyWe propose a novel SDN control and orchestration architecture to provide composed IaaS over optical disaggregated data centers. We experimentally validate intent-based mechanisms that make the architecture independent from ... -
Single sideband techniques for next generation low-cost UD-WDM coherent PONs
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Restricted access - publisher's policyTwo applications for splitter-based, coherent passive optical networks are investigated. Coherent technologies enable ultra-dense wavelength division multiplexing, increasing the dedicated data rates per application, the ... -
Quantum bit retransmission using universal quantum copying machine
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessQuantum internet, which is expected to be a combination of quantum and classical networks, promises to provide information-theoretic security for data exchange. Classical networks have well-established protocols for reliable ... -
Dual time and frequency domain optical layer digital twin
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessWe demonstrate a digital twin for failure detection in optical networks. Artificial neural networks-based models for optical constellation analysis enable predicting the transmitted signal in the time domain whereas ... -
Multi-agent-based dynamic optical subcarrier allocation for near real-time P2MP operation
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessWe propose a multi-agent system (MAS) to manage subcarrier allocation in point-to-multipoint connectivity based on Digital Subcarrier Multiplexing. Similar performance to a centralized approach is shown, which allows for ... -
Designing a digital twin for quantum key distribution
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessClassical optical devices lack precision when they operate on single photons. We report a Quantum Digital Twin (QDT) to improve Quantum Key Distribution (QKD) implementations. We show a QDT increasing the Key Exchange Rate ... -
Dynamic subcarrier allocation for multipoint-to-point optical connectivity
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessA mathematical programming model is proposed to dynamically allocate subcarriers in the upstream direction of point-to-multipoint connections based on Digital Subcarrier Multiplexing. Numerical results show significant ... -
An escape room for an alternative evaluation system
(Universidade do Minho, 2022)
Conference lecture
Open AccessOur traditional education system spins around evaluation and its traditional grading system: summative assessment. In that system, professors spend time and effort trying to be “fair” when they mark the exercises, while ... -
Dynamic and efficient point-to-point and point-to-multipoint communications by slicing the optical constellation
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference lecture
Open AccessOptical Constellation Slicing is proposed to convey heterogenous traffic from a source to multiple destinations, while supporting dynamic capacity allocation. Illustrative numerical results reveal the potential of the ... -
Experimental demonstration of SDN-enabled reconfigurable disaggregated data center infrastructure
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Restricted access - publisher's policyA 4-node prototype of SDN-controlled disaggregated data-center network is experimentally demonstrated based on the nanoseconds optical switch, enabling flexible hardware resource provisioning and dynamic resource reallocation. ...
