Research Interests

Dr. Boyd is currently performing research in the areas of integrated photonics and optical-MEMS structures. He has performed significant research in nonlinear optics and optical material characterization. Dr. Boyd's research has involved advanced photonic materials such as compound semiconductors and polymers directed at applications in high speed information processing, research on silicon-based devices for sensor applications, and research on LiNbO3 devices for both sensor and information processing. Material characterization has used techniques such as Raman microprobe spectroscopy, photoluminescence, optical waveguide loss measurements, and near field scanning optical microscopy (NSOM) and spectroscopy. Theoretical modeling continues to be performed both to explore novel device concepts and to support many aspects of his experimentation.
