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 …

Congratulations to Emerson and all the team! This is our first paper on plasmonics structures! Check it out at https://doi.org/10.1021/acsanm.9b02508
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 …
Congratulations to PhD candidate André Primo! Got awarded for his outstanding talk on bolometric optical forces at the SBFoton conference 2019!
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 …
