Brief Biography and Research Highlights
Dr. Harrington has over thirty years of research experience in the area of optical properties of solids. Since 1977, he has worked on all aspects of infrared fibers including fabrication, characterization, and applications. He is generally recognized as one of the world's leading experts in this continually evolving field. His current research interests include the development of fiber optics for use in the delivery of laser power in surgical and industrial applications and for use as chemical and thermal fiber sensors. Specifically, these new fibers include hollow glass waveguides and solid core, single-crystal sapphire fibers for the delivery of CO₂, Er:YAG, and FEL laser radiation. These same waveguides are also being used as fiber links in spectroscopic and thermometric applications aimed at the identification of chemical species and the measurement of low and high (>1500 ^oC) temperature radiation. As Director of Infrared Fiber Operations for Heraeus LaserSonics, he led the research and development of infrared fiber optics for delivering CO₂ laser power in surgical applications. He was the inventor of both the hollow sapphire and hollow glass waveguides which today are being used as CO₂ laser delivery systems in gynecology, arthroscopy, and dentistry. Other research activities include the development of diffusing-tip silica fibers for use in photodynamic therapy (PDT) and prostate surgery, thin film coatings for hollow waveguides, and infrared fibers for use in an Army -sponsored, CO₂ laser-threat warning receivers.
