Raman Self-Frequency Shift of Dissipative Kerr Solitons in an Optical Microresonator

Tobias Kippenberg, Victor Brasch, Michail Zervas, Michael Wolfgang Geiselmann, Maxim Karpov, Hairun Guo, Martin Hubert Peter Pfeiffer, Arne Kordts

We experimentally observed the Raman-induced self-frequency shift of high-intensity dissipative Kerr solitons in high-Q silicon nitride microresonators. The Raman redshift is linearly dependent on the pump-frequency-detuning, associated with the tunability ...

Thin-film-specific elastic effects in ferroelectric domain structures

Konstantin Shapovalov

An essential feature of ferroelectric thin films is the presence in them of domain structures. In order to efficiently implement ferroelectric films into potential new ferroelectrics-based devices, it is of high interest to understand the behaviour of doma ...

Q-holes

Andrey Shkerin

We consider localized soliton-like solutions in the presence of a stable scalar condensate background. By the analogy with classical mechanics, it can be shown that there may exist solutions of the nonlinear equations of motion that describe dips or rises ...

Resonant elastic x-ray scattering from the skyrmion lattice in Cu2OSeO3

Helmuth Berger

We report the study of the skyrmion state near the surface of Cu2OSeO3 using soft resonant elastic x-ray scattering (REXS) at the Cu L-3 edge. Within the lateral sampling area of 200 x 200 mu m(2), we found a long-range-ordered skyrmion lattice phase as we ...

Skyrmion dynamics under uniaxial anisotropy

Dirk Grundler

Broadband microwave spectroscopy has been performed on single-crystalline GaV4S8, which exhibits a complex magnetic phase diagram including cycloidal and Neel-type skyrmion lattice phases below 13 K. At small magnetic fields two collective modes with large ...

Soliton Kerr Frequency Combs Generated in Integrated Photonic Chips

Victor Brasch

In 2007 a new method to generate optical frequency combs was discovered. In contrast to conventional frequency combs which are generated from pulsed laser sources, these Kerr frequency combs (also known as microresonator frequency combs) are generated enti ...

The GBS code for tokamak scrape-off layer simulations

Paolo Ricci, Joaquim Loizu Cisquella, Trach-Minh Tran, Sébastien Jolliet, Federico David Halpern, Fabio Riva, Annamaria Mosetto, Christoph Wersal

We describe a new version of GBS, a 3D global, flux-driven plasma turbulence code to simulate the turbulent dynamics in the tokamak scrape-off layer (SOL), superseding the code presented by Ricci et al. (2012) [14]. The present work is driven by the object ...

Generating optical pulses via a soliton state of an optical microresonator

Tobias Kippenberg, Tobias Herr

A light pulse source (100), being adapted for generating repetitive optical pulses, comprises a continuous wave (cw) laser (10) being arranged for providing cw laser light, an optical microresonator (20) being made of a resonator material, which has a thir ...

Multidomain Skyrmion Lattice State in Cu2OSeO3

Helmuth Berger

Magnetic skyrmions in chiral magnets are nanoscale, topologically protected magnetization swirls that are promising candidates for spintronics memory carriers. Therefore, observing and manipulating the skyrmion state on the surface level of the materials a ...

Imaging and manipulation of skyrmion lattice domains in Cu2OSeO3

Helmuth Berger

Nanoscale chiral skyrmions in noncentrosymmetric helimagnets are promising binary state variables in high-density, low-energy nonvolatile memory. Skyrmions are ubiquitous as an ordered, single-domain lattice phase, which makes it difficult to write informa ...
