By bringing nanophotonics technology to traditional optical spectroscopy, a new kind of optical spectrometer with functions of sensing and spectral measurement has been recently demonstrated by a research team at The University of Alabama in Huntsville. Dr. Junpeng Guo, Associate Professor of Electrical Engineering and Optics at UAHuntsville, recently created a new nanoscale photonic device called a super nano-grating, with the assistance of his doctoral student, Haisheng Leong. With a fabricated super nano-grating, Dr. Guo’s group demonstrated a new kind of optical sensing apparatus called spectrometer sensors.
