Cryo-CMOS for Analog/Mixed-Signal Circuits and Systems

CMOS circuits operating at cryogenic temperature (cryo-CMOS) are required in several low-temperature applications. A compelling example is the electronic interface for quantum processors, which must reside very close to the cryogenic quantum devices it ser ...

Quantifying and optimizing photocurrent via optical modeling of gold nanostar-, nanorod-, and dimer-decorated MoS2 and MoTe2

Theodoros Tsoulos

Finite element simulations through COMSOL Multiphysics were used to optically model systems composed of Mo dichalcogenide layers (MoTe2 and MoS2) and Au nanoparticles (spherical dimers, nanorods, and nanostars) to understand how their fundamental material ...

Optical gap and fundamental gap of oligoynes and carbyne

Holger Frauenrath, Jan Cornelius Brauer, Stephen Schrettl, Laurent Alexis Clément Vannay, Eric Albert Georges Bremond, Emmanuel Romaric Contal

The optoelectronic properties of various carbon allotropes and nanomaterials have been well established, while the purely sp-hybridized carbyne remains synthetically inaccessible. Its properties have therefore frequently been extrapolated from those of def ...

Peculiarities of second harmonic generation with chirped femtosecond pulses at high conversion efficiency

Pierre-Marc Jean Marie Dansette

Frequency doubling of an infrared laser radiation in non-linear optical crystals is a widely used technique to obtain light in the visible range. The second harmonic generation process is influenced by several well-known parameters. In this article we stud ...

Subthreshold Mismatch in Nanometer CMOS at Cryogenic Temperatures

Edoardo Charbon, Fabio Sebastiano

Cryogenic device models are essential for the reliable design of the cryo-CMOS electronic interface necessary to build future large-scale quantum computers. This paper reports the characterization of the drain-current mismatch of NMOS and PMOS devices fabr ...

Formation and Collision of Multistability-Enabled Composite Dissipative Kerr Solitons

Tobias Kippenberg, Wenle Weng

Multistability in Kerr resonators which are driven by continuous or modulated optical waves gives rise to the superposition of distinct nonlinear states, yielding a unique platform for studying complex soliton dynamics. Here, by pumping a crystalline micro ...

Roadmap on all-optical processing

Simon Julien Fabbri, Xiang Zhang

The ability to process optical signals without passing into the electrical domain has always attracted the attention of the research community. Processing photons by photons unfolds new scenarios, in principle allowing for unseen signal processing and comp ...

Integrated Si3N4 Soliton Microcomb Driven by a Compact Ultra-low-noise Laser

Tobias Kippenberg, Rui Ning Wang, Nicolas Volet, Junqiu Liu, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Jijun He

We generate 100-GHz soliton microcombs in a photonic integrated high-Q Si3N4 microresonator using an ultra-compact, high-power and low-frequency-noise semiconductor-based laser. The soliton is initiated via direct current tuning of the laser. (C) 2019 The ...
