Contra-Intuitive Features of Time-Domain Brillouin Scattering in Collinear Paraxial Sound and Light Beams
Vitalyi E. Gusev
Time-domain Brillouin scattering is an opto-acousto-optical probe technique for the evaluation of the transparent materials. Ultrashort pump laser pulses via optoacoustic conversio…
Ultrafast tunable modulation of light polarization at terahertz frequencies
Vincent Juvé, Gwenaëlle Vaudel, Zoltan Ollmann +4
Controlling light polarization is one of the most essential routines in modern optical technology. Since the demonstration of optical pulse shaping by spatial light modulators and…
Granular Graphene: direct observation of zigzag and armchair edge waves
Li-Yang Zheng, Florian Allein, Vincent Tournat +2
We propose a mechanical granular graphene obtained by replacing the carbon atoms with macroscopic spherical stainless steel beads in contact. The experimental measured dispersion r…
Advances in applications of time-domain Brillouin scattering for nanoscale imaging
Vitalyi E. Gusev, Pascal Ruello
Time-domain Brillouin scattering is an all-optical experimental technique based on ultrafast lasers applied for generation and detection of coherent acoustic pulses on time duratio…
