Reconfigurable optical generation of nine Nyquist WDM channels with sinc-shaped temporal pulse trains using a single microresonator-based Kerr frequency comb

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Fatemeh Alishahi, Ahmad Fallahpour, Amirhossein Mohajerin Ariaei, Cong Liu

Sinc-shaped temporal pulse trains have a spectrally efficient, rectangular Nyquist spectrum. We demonstrate the simultaneous and reconfigurable optical generation of multiple Nyquist-shaped wavelength-division-multiplexed (WDM) channels having temporal sin ...

A programmable low-power ADC interface for an ISFET sweat sensor used in a wearable multi-sensing system

Maher Kayal, Evgenia Voulgari, François Krummenacher

An application specific integrated circuit (ASIC) named ANTIGONE (ANalog To dIGital cONvErter) was designed in AMS 0.35 mu m technology to interface with four Ion-sensitive field-effect transistor (ISFET) sensors and perform real-time monitoring of some bi ...

V-band nanosecond-scale pulse reflectometer diagnostic in the TCV tokamak

Stefano Coda, Laurie Porte, Pedro Andres Molina Cabrera

This article describes the realization of a novel approach to short pulse (∼1 ns) reflectometry (SPR) recently implemented in the tokamak configuration variable tokamak. Taking advantage of a fast arbitrary waveform generator and vector-network-analyzer ex ...

Near Hysteresis-Free Negative Capacitance InGaAs Tunnel FETs with Enhanced Digital and Analog Figures of Merit below VDD=400mV

Mihai Adrian Ionescu, Igor Stolichnov, Ali Saeidi, Hiroshi Iwai

We report the universal boosting impact of a true negative capacitance (NC) effect on digital and analog performances of Tunnel FETs (TFETs), mirrored for the first time in near hysteresis-free experiments and exploiting the S-shaped polarization character ...

Design of an Energy-Efficient Current-to-Frequency Converter for a Wearable Sensor Platform

Maher Kayal, Evgenia Voulgari, François Krummenacher

This paper presents the design of the ANTIGONE ASIC in AMS 0.35 mu m technology that interfaces with ion-sensitive field effect transistors (ISFETs) to detect biomarkers like pH, Na+ and K+ in human sweat. The ISFET sensors generate a low current dc signal ...

Second- and third-order nonlinear wavelength conversion in an all-optically poled Si3N4 waveguide

Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Martin Hubert Peter Pfeiffer

Silicon nitride (Si3N4) is commonly employed to integrate third-order nonlinear optical processes on a chip. Its amorphous state, however, inhibits significant second-order nonlinear response. Recently, second-harmonic generation enhancement has been obser ...
