Lithium-Niobate-Based Frequency-Agile Integrated Lasers

Tobias Kippenberg, Rui Ning Wang, Anat Siddharth, Mikhail Churaev, Viacheslav Snigirev, Grigorii Likhachev, Junqiu Liu, Guanhao Huang

We demonstrate narrow- linewidth ultrafast tunable integrated lasers based on heterogeneously integrated thin-film lithium niobate on ultra-low loss silicon nitride integrated photonic circuits. Using self-injection locking of a hybrid microresonator, we a ...

Repetitive regime of highly focused liquid microjets for needle-free injection

Christophe Moser, Paul Delrot, Jan Krizek

Fast liquid jets are investigated for use as a needle-free drug delivery system into an elastic tissue such as skin. Using smaller jet diameters in a repetitive regime can mitigate bruising and pain associated with current injectors. In this study, we aim ...

Dynamics of Soliton Microcomb Self-Injection Locking in a Silicon Nitride Microresonator

Tobias Kippenberg, Junqiu Liu, Andrey Voloshin

We demonstrate a chip-scale 30 GHz single soliton microcomb based on DFB laser locked to a Si3N4 microresonator. We propose novel theoretical and experimental approaches to explain dynamics of self-injection locking, modified by Kerr nonlinearity. (c) 2020 ...

Facile Fabrication of Microfluidic Chips for 3D Hydrodynamic Focusing and Wet Spinning of Polymeric Fibers

Fabien Sorin, René M. Rossi, Efe Armagan, Claudio Toncelli, Akin Gürsoy

Microfluidic wet spinning has gained increasing interest in recent years as an alternative to conventional wet spinning by offering higher control in fiber morphology and a gateway for the development of multi-material fibers. Conventionally, microfluidic ...

A high sensitivity low-power capacitive front-end for insulin injection pens

Maher Kayal, François Krummenacher, Jean-Baptiste Robert Orhan, François Pierre Gaugaz

A low-power 14-bits first order incremental Analog-to-Digital Converter (ADC) is presented. Based on the charge balancing principle, this switched-capacitor (SC) circuit integrates the input signal multiple times to reach the targeted resolution, linearity ...

Needle for invasive medical use and needle assembly

Simon Nessim Henein, Charles Baur

A needle for invasive medical use includes a long extended cylindrical needle shaft having an axis and an outer surface area, with a short shaft end at a first end of the shaft with a beveled tip with a pointed end, and a needle hub attached to a second en ...

Injection Device

Yves Perriard, Romain David Besuchet

An injection deviee for injecting injection material, comprising: an elastic deformable element (3) able to exert a pushing force on a piston (20) of a syringe (2) so as to eject a quantity of injection material out of the syringe (2); a stopper ( 4) for r ...

Experiments in a novel quasi-1D diffusion flame with variable bulk flow

Peter Monkewitz, Etienne Robert

The novel species injector of a recently developed research burner, consisting of an array of hypodermic needles, which allows to produce quasi one-dimensional unstrained diffusion flames has been improved. It is used in a new symmetric design with fuel an ...

Experimental investigation of unstrained diffusion flames and their instabilities

Etienne Robert

In this thesis, thermal-diffusive instabilities are studied experimentally in diffusion flames. The novel species injector of a recently developed research burner, consisting of an array of hypodermic needles, which allows to produce quasi one-dimensional ...
