Brillouin optomechanics tutorial is out!

Brillouin optomechanics in nanophotonic structure APL Photonics 4, 071101 (2019);   This tutorial guides and motivates scientists delving into the core of light-sound interaction. Through tangible examples, we lay out key concepts underneath accurate prediction of Brillouin gain in optomechanical structures. We have also published a data set at Zenodo repository with all the …
