Fiber-based angular filtering for high-resolution Brillouin spectroscopy in the 20-300 GHz frequency range
A. Rodriguez, Priya, O. Ortiz +5
Brillouin spectroscopy emerges as a promising non-invasive tool for nanoscale imaging and sensing. One-dimensional semiconductor superlattice structures are eminently used for sele…

Brillouin Scattering in Hybrid Optophononic Bragg Micropillar Resonators at 300 GHz
M. Esmann, F. R. Lamberti, A. Harouri +9
We introduce a monolithic Brillouin generator based on a semiconductor micropillar cavity embedding a high frequency nanoacoustic resonator operating in the hundreds of GHz range.…
