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 …
Fourier transform spectrometer on silicon with thermo-optic non-linearity and dispersion correction
Congratulations to Mario! In a recent collaboration between prof. Newton Frateschi and Mario Souza with prof. Yeshaiahu Fainman from UCSD our team has published a new design for a fourier transform spectrometer. Media Highlights: Espectrômetro de infravermelho que cabe em um chip (Portuguese version) Infrared spectrometer on a chip (English version) Un espectrómetro de infrarrojo …
