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

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 …

André receives SBFOTON award for his excellent talk

Congratulations to PhD candidate André Primo! Got awarded  for his outstanding talk on  bolometric optical forces at  the SBFoton conference 2019! 

Several postdoc positions available at our group!

Please check our post-doc  Opportunities. Application deadline coming up soon in late October and early November!

Check-out our Brillouin optomechanics tutorial publication!

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 simulation files and data to generate every and each paper’s figures.  Brillouin …
