Integrated Magnetic-free Nitride Optical Isolator

Tobias Kippenberg, Rui Ning Wang, Anat Siddharth, Junqiu Liu, Jijun He

We demonstrated an integrated magnetic-free optical isolator for Si3N4 photonics using AlN piezoelectric actuators via spatio-temporal modulation. By entering into the strong mode coupling regime, maximum of 9dB isolation and

Statically and dynamically balanced oscillator based on Watt's linkage

Simon Nessim Henein, Hubert Pierre-Marie Benoît Schneegans, Ilan Vardi

We present a new mechanical oscillator architecture that can be made insensitive to linear and angular accelerations while keeping constant oscillation frequency. The oscillator has the kinematics of a Watt linkage, so we call it a Watt oscillator. In orde ...

Power calibration methodology at the CROCUS reactor

Andreas Pautz, Vincent Pierre Lamirand, Oskari Ville Pakari, Pavel Frajtag, Axel Guy Marie Laureau

In the present article, we detail the method used to experimentally determine the power of the CROCUS zero-power reactor, and to subsequently calibrate its ex-core monitor fission chambers. Knowledge of the reactor power is a mandatory quantity for a safe ...

Analysis of the lightning production of convective cells

Marcos Rubinstein, Mohammad Azadifar, Antonio Sunjerga, Amirhossein Mostajabi, Jacopo Grazioli, Nikola Besic, Urs Martin Germann

This paper presents an analysis of the lightningproduction of convective cells. The cells were detected by the MeteoSwiss Thunderstorms Radar Tracking (TRT) algorithm in the course of a lightning measurement campaign thattook place in the summer of 2017 in ...

Benchmarking of Homojunction Strained-Si NW Tunnel FETs for Basic Analog Functions

Mihai Adrian Ionescu, Cem Alper, Arnab Biswas, Florin Udrea

This paper reports a compact ambipolar model for homojunction strained-silicon (sSi) nanowire (NW) tunnel FETs (TFETs) capable of accurately describing both I-V and G-V characteristics in all regimes of operation, n- and p-ambipolarity, the superlinear ons ...

Harvesting Energy From a Rotating Gear Using an AFM-Like MEMS Piezoelectric Frequency Up-Converting Energy Harvester

Nico de Rooij, Danick Briand, Simon Nessim Henein, Pattanaphong Janphuang, Robert Andrew Lockhart, Don Isarakorn

This paper presents an analytical and experimental study of a compact configuration to harvest energy from a rotating gear using piezoelectric microelectromechanical system harvesters. The reported configuration realizes a contact-type frequency up-convers ...

Scaling the Memory Power Wall with DRAM-Aware Data Management

Anastasia Ailamaki, Raja Appuswamy, Matthaios Alexandros Olma

Improving the energy efficiency of database systems has emerged as an important topic of research over the past few years. While significant attention has been paid to optimizing the power consumption of tradition disk-based databases, little attention has ...

Development and integration of high straightness flexure guiding mechanisms dedicated to the METAS watt balance Mark II

Reymond Clavel, Florent Cosandier

There is a firm will in the metrology community to redefine the kilogram in the International System of units by linking it to a fundamental physical constant. The watt balance is a promising way to link the mass unit to the Planck constant h. At the Feder ...
