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 ...

Degradation study on molecules released from laser-based jet injector

Christophe Moser, Jan Krizek, Barbora Lavickova

Development of needle-free methods to administer injectable therapeutics has been researched for a few decades. We focused our attention on a laser-based jet injection technique where the liquid-jet actuation mechanism is based on optical cavitation. This ...

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 ...

Electrically driven photonic integrated soliton microcomb

Tobias Kippenberg, Maxim Karpov, Junqiu Liu, Hairun Guo, John David Jost, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Andrey Voloshin

We demonstrate via self-injection locking an electrically driven soliton micro-comb by coupling a multi-frequency laser diode to a chip-scale high-Q Si3N4 microresonator. This approach offers a pathway for an integrated and ultra-compact microcomb source f ...

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 ...

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 ...
