“Quasinormal-Mode Perturbation Theory for Dissipative and Dispersive Optomechanics” on PRL
André and team got their Christmas gift earlier in 2020 with this PRL publication! Check out the repercussion on several news outlets.
“Alumina coating for dispersion management in ultra-high Q microresonators” highlighted as “featured article” in APL Photonics!
Marvyn’s effort has payed off and his work was chosen as featured article in APL Photonics (November edition)
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 …

Our plasmonic colors just came out in ACS Applied Nano Materials
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
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 …
