Check out this preprint (https://arxiv.org/abs/2009.07826)! Accompanying datasets and COMSOL simulation scripts are available on Zenodo (https://doi.org/10.5281/zenodo.3932243). Silica optical microspheres often exhibit ultra-high quality factors, yet, their group velocity dispersion, which is crucial for nonlinear optics applications, can only be coarsely tuned. We experimentally demonstrate that group-velocity dispersion of a silica microsphere can be engineered by …

New paper on GaAs optomechanics just published in Optical Materials Express. Congratulations Rodrigo!
A method to fabricate GaAs microcavities using only a soft mask with an electrolithographic pattern in an inductively coupled plasma etching is presented. A careful characterization of the fabrication process pinpointing the main routes for a smooth device sidewall is discussed. Using the final recipe, optomechanical microdisk resonators are fabricated. The results show very high …
Brillouin optomechanics tutorial is out!
Brillouin optomechanics in nanophotonic structure APL Photonics 4, 071101 (2019); https://doi.org/10.1063/1.5088169 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 …
