Terabit direct-detection optical engines and switching circuits in multi-chip modules for Data-center networks and the 5G optical fronthaul Interuniversitair Micro-Electronica Centrum vzw
Terabit capacity optical engines for data center and access networks are gaining momentum supported by a pool of technological innovations that are promising low cost and simple design for a wide range of application use cases.
Deep Proton Writing: A tool for rapid prototyping of polymer micro-opto-mechanical modules Vrije Universiteit Brussel
One of the important challenges to prototype optical and micro-optical systems is the ability to include geometries with high enough optical surface quality. This generally means that the surface flatness and The resolution should be controlled within a sub-micrometer scale and that the resulting surface roughness should be only a fraction of the operating wavelengths. In our labs at the Vrije Universiteit Brussel we are therefore focusing on ...
Real-Life Mission Profile Oriented Lifetime Estimation of a SiC Interleaved Bidirectional HV DC/DC Converter for Electric Vehicle Drivetrains Vrije Universiteit Brussel
The rapid growth of Battery Electric Vehicles (BEVs) in the automotive field has led to a need for improving their drivetrain performance, mainly focusing on the extension of the battery operating range. However, the majority of performed technical assessments only consider battery SoC and depth of discharge while neglecting the effects on lifetime and failure probability of power electronic components, more specifically the emerging ...
Delay Analysis of a Multi-Hop Strict Priority Scheduler Interuniversitair Micro-Electronica Centrum vzw Universiteit Antwerpen
Strict priority schedulers are often used in IP networks to guarantee delays for traffic that has strict delay requirements. There is literature for single node bounds for some priorities, however, for end-to-end delay bounds through-traffic is often ignored, which can be crucial in obtaining correct end-to-end bounds. In this paper we give an upper bound on the end-to-end delay and delay variation distributions for all the priorities in a ...

Reliable and Energy Efficient Network Protocols for Wireless Body Area Networks Universiteit Gent
In a wireless Body Area Network (WBAN) various sensors are attached on clothing, on the body or are even implanted under the skin. The wireless nature of the network and the wide variety of sensors offers numerous new, practical and innovative applications. A motivating example can be found in the world of health monitoring. The sensors of the WBAN measure for example the heartbeat, the body temperature or record a prolonged electrocardiogram. ...
On the network design and control of an optical network : interconnecting multiple chips on a wafer Universiteit Gent
In this paper, we propose a network architecture for a multi-chip optical network-on-wafer (NoW); we concentrate on the research of its control mechanisms and control algorithms. Our proposed optical NoW aims at providing dynamically controlled terabytes-per-second unidirectional bandwidth for every chip module in a multi-chip processor. This architecture is promising in achieving low energy consumption and high aggregated bandwidth, providing a ...
