Marvyn’s dispersion engineering with alumina is on arXiv!
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 …
