The effect of low-frequency equalisation on preference and sensorimotor synchronisation in music

Equalisation, a signal processing technique commonly used to shape the sound of music, is defined as the adjustment of the energy in specific frequency components of a signal. In this work, we investigate the effects of equalisation on preference and senso ...

Frequency division using a soliton-injected semiconductor gain-switched frequency comb

Tobias Kippenberg, Junqiu Liu, Wenle Weng

With optical spectral marks equally spaced by a frequency in the microwave or the radio frequency domain, optical frequency combs have been used not only to synthesize optical frequencies from microwave references but also to generate ultralow-noise microw ...

Frequency Division Using a Soliton-Injected Semiconductor Gain-Switched Frequency Comb

Tobias Kippenberg, Junqiu Liu, Wenle Weng

By injecting a soliton microcomb into a semiconductor laser that is driven by a sinusoidal current at the subharmonic frequencies of the soliton rate, we demonstrate broadband gain-switched frequency comb generation and low-noise microwave synthesis. (C) 2 ...

Wide band-pass FSS with reduced periodicity for energy efficient windows at higher frequencies

Josef Andreas Schuler, Luc Burnier, Jérémy Jacques Antonin Fleury

A simulation model and an experimental characterization of energy saving glazing transparent to mobile communication frequency up to 40 GHz is presented. A previous study showed that laser structured energy efficient windows with a frequency selective surf ...

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 ...

Monolithic piezoelectric control of soliton microcombs

Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Erwan Guillaume Albert Lucas, Wenle Weng, Arslan Sajid Raja, Jijun He, Miles Henry Anderson, Tianyi Liu

High-speed actuation of laser frequency(1)is critical in applications using lasers and frequency combs(2,3), and is a prerequisite for phase locking, frequency stabilization and stability transfer among optical carriers. For example, high-bandwidth feedbac ...
