Beyond 8 THz Displacement-field Nano-switches for 5G and 6G Communications

Mihai Adrian Ionescu, Elison de Nazareth Matioli, Pirouz Sohi, Riyaz Mohammed Abdul Khadar

The rapid progress in high capacity communication systems is reaching extremely high data rates of 100 Gb s−1, which demands electronic switches with cut-off frequencies well above 1 THz. The excellent electron transport properties of III-V heterojunctions ...

RRAM-VAC: A Variability-Aware Controller for RRAM-based Memory Architectures

David Atienza Alonso, Alexandre Sébastien Julien Levisse, Marco Antonio Rios, Shikhar Tuli

The growing need for connected, smart and energy efficient devices requires them to provide both ultra-low standby power and relatively high computing capabilities when awoken. In this context, emerging resistive memory technologies (RRAM) appear as a prom ...

Electromagnetic Performance of RF NEMS Graphene Capacitive Switches

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Julien Perruisseau-Carrier, Pankaj Sharma

The RF performance of a nanoelectromechanical systems (NEMS) capacitive switch based on graphene is evaluated. Our results show that graphene can be a good candidate for the membrane of RF NEMS switches in applications where low actuation voltage and fast ...

Large mode splitting and lasing in optimally coupled photonic-crystal microcavities

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Kirill Atlasov

Coupling of L-type photonic-crystal (PhC) cavities in a geometry that follows inherent cavity field distribution is exploited for demonstrating large mode splitting of up to similar to 10-20 nm (similar to 15-30 meV) near 1 mu m wavelength. This is much la ...

RVC: a Multi-Decoder CAL Composer tool

Marco Mattavelli, Ghislain Roquier

The Reconfigurable Video Coding (RVC) framework is a recent ISO standard aiming at providing a unified specification of MPEG video technology in the form of a library of components. The word “reconfigurable” evokes run-time instantiation of different decod ...

Fast Dimensioning of Packet-Switched All-Optical Networks

This paper addresses the basic concepts of the packet switching in the optical domain and describes an analytical approach to evaluate the end-to-end performance of networks employing slotted (fixed length) optical packets. Thus, for a given topology and t ...

Modeling and performance analysis of IP access interface in optical transmission networks with packet switching

The article analyzes the influence of the Internet Protocol (IP) access interface on the packet loss probability and delay times in the optical packet switched network. The network and node model have been proposed, and the structure of the IP access inter ...

Performance analysis of packet switched all-optical networks

All-optical packet switching has been intensively investigated in recent years as an alternative to static, crossconnect based networks. Several switch architectures have been proposed, all of them using buffers made of fibre delay lines. The paper address ...

Control design of hybrid systems via dehybridization

Babak Sedghi

Hybrid dynamical systems are those with interaction between continuous and discrete dynamics. For the analysis and control of such systems concepts and theories from either the continuous or the discrete domain are typically readapted. In this thesis the i ...

30 kV/10 mA solid state anode modulator for gyrotron plasma heating: design issues and results

Damien Fasel

Three 30 kV/10 mA solid state pulsed modulators have been delivered to the CRPP in Lausanne, by the company JEMA. Each modulator supplies the anode grid of a triode type gyrotron, used for heating purpose at the third harmonic in the TCV Tokamak. The main ...
