Heteronuclear soliton molecules in optical microresonators

Tobias Kippenberg, Erwan Guillaume Albert Lucas, Wenle Weng, Tobias Herr

Optical soliton molecules are bound states of solitons that arise from the balance between attractive and repulsive effects. Having been observed in systems ranging from optical fibres to mode-locked lasers, they provide insights into the fundamental inter ...

Attenuation of Lamb Modes and SH Waves near cut-off Frequencies

Soumya Yandrapalli, Victor Plessky

Near cut-off frequencies, the shear horizontal (SH) and Lamb modes in a platelet are created by a bulk acoustic wave bouncing up and down between the platelet sides in an almost vertical direction. The small inclination angle corresponds to slow drift of e ...

Strongly Coupled Coherent Phonons in Single-Layer MoS2

Andras Kis, Dumitru Dumcenco

We present a transient absorption setup combining broadband detection over the visible-UV range with high temporal resolution (similar to 20 fs) which is ideally suited to trigger and detect vibrational coherences in different classes of materials. We gene ...

Opto-mechanical cross-talk reduction in air-holes multicore fibers

Luc Thévenaz, Zhisheng Yang, Simon Adrien Zaslawski, Yun Fu

We report on the use of air-holes in multicore fibers to alleviate intercore perturbations induced by forward stimulated Brillouin scattering. Comparisons with conventional multicore fibers show significant improvement in terms of cross-talk reduction. ...

Arbitrarily high time bandwidth performance in a nonreciprocal optical resonator with broken time invariance

Camille Sophie Brès, Hatice Altug, Davide Grassani, Ivan Cardea, Kosmas Tsakmakidis, Simon Julien Fabbri

Most present-day resonant systems, throughout physics and engineering, are characterized by a strict time-reversal symmetry between the rates of energy coupled in and out of the system, which leads to a trade-off between how long a wave can be stored in th ...

Photonic chip-based resonant supercontinuum generation with intrinsic nonlinear filtering

Tobias Kippenberg, Junqiu Liu, Wenle Weng, Tobias Herr, Miles Henry Anderson

We demonstrate broadband soliton-based resonant supercontinuum generation in a chip-based microresonator. We show that the soliton possesses an intrinsic ability to filter RF noise transfer from the input pulses, which can be further improved with asynchro ...

Resonant dissipative Kerr soliton supercontinuum in the normal dispersion regime

Tobias Kippenberg, Junqiu Liu, Tobias Herr, Miles Henry Anderson

We demonstrate broadband resonant supercontinuum generation in a Si3N4 microresonator with normal dispersion. Rectangular bright pulses are shown to form directly using synchronous pulse-driving, generating a 2,600-line comb at 28 GHz repetition rate. (C) ...

Level-line moirés by superposition of cylindrical microlens gratings

Jürgen Brugger, Roger Hersch, Thomas Walger, Valentin Flauraud, Théophane Besson

Two superposed layers of transparent cylindrical lenslet gratings create classical moiré fringes when illuminated from behind. We rely on this observation to conceive special devices made of superposed lenslet gratings that produce compelling beating shape ...
