Researchers from Souza's University of Campinas and the University of California San Diego have developed a Fourier-transform Infrared spectrometer based on silicon photonics, making it small enough to use in a smartphone or drone. In an article published in Nature Communications, the team used a laser calibration method to overcome silicon's non-linear distortions, creating a chip that had a broadband spectrum with a resolution of 0.38THz. The researchers are now working on integrating a light source and photodetectors.
