Today's Colloquium: 3:30 p.m. Meinel 307
Abstract: Fiber lasers have attracted significant attention in the last several years because of many technology breakthroughs and commercial business successes. Most fiber lasers use rare-earth ions doped silica fibers as the gain media. However, in many cases silica fiber is not the ideal host. Multi-component specialty glass fibers are good alternatives because of their unique features such as low co-operative up-conversion coefficient, large mode field diameter, and short active fiber length. In this presentation, I will present highly erbium and ytterbium doped phosphate glass fibers for narrow linewidth single frequency fiber lasers near 1.5 and 1 microns, and thulium doped germanate glass fiber 2 micron fiber lasers with slope efficiency great than 70%. Brillouin fiber laser, Brillouin based fiber sensing, and potential application for wireless-over-fiber will be discussed. THz and GHz generation using Q-switched high power fiber lasers will also be described in this presentation.
April 23 3:00 p.m. Meinel 821: Special Presentation
Dr. Paul F. McManamon, Past President of SPIE and Chief Scientist, Sensors Directorate, Air Force Research Laboratory, will present The Partial Derivative of Layered Sensing With Respect to Optics and Photonics. All OSC students, faculty, and staff are invited to attend.
Next Week's Colloquium: 3:30 p.m. Meinel 307
Abstract: Infrared-transmissive hollow waveguides (HWGs) are enjoying a resurgence resulting from emerging applications in a variety of sensor and power delivery systems. These HWGs consist of glass or polymer tubes with highly reflective metallic and dielectric coatings deposited on the inside surface. They are normally fabricated for transmission from transmit from 2 to 12 µm but they have also been made for the transmission of visible and THz radiation. Losses in the IR regime are less than 1 dB/m and lengths as long as 10 m have been made. The most successful structure has been the Ag/AgI coated hollow silica waveguides which are now being used to transmit broadband spectral information for thermal imaging and spectroscopy as well as for IR laser surgery. A brief history of the development of these unique structures will be given followed by a more detailed description of the optical properties of the HWGs. A variety of applications will be described including those involving laser power delivery in surgery, thermal imaging, and spectroscopy.
In addition to the technical presentation on hollow waveguides, I will also briefly describe my year working as a scientist at the Department of State. While there is generally a paucity of scientists at State, I found that scientists can play a key role assisting our foreign policy makers on science related issues. My year at State was spent as the science advisor for the control of dual-use, high technology items which the US controls either though the Department of Commerce or Defense (ITAR). I will review my year at State including examples of what types of technologies are controlled along with my work on visa related issues. During my year I have seen first hand the importance of science in the development of a sound foreign policy. Clearly there is an important role for a scientist at State yet I have learned that even though the science may be straightforward the path to achieving the final export controls is often filled with diplomatic potholes.
Bio: Dr. Harrington has over thirty-five 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 and for spectroscopic and thermometric applications aimed at the identification of chemical species and the measurement of low and high (>1500 C) temperature radiation. He is the inventor of hollow glass waveguides, which today are being used as CO2 laser delivery systems in gynecology, arthroscopy, and dentistry. His book, Infrared Fibers and Their Applications, SPIE Press, January, 2004 provides a comprehensive overview of IR fiber optics and an entry point for those wishing to learn more about this growing field.
Dr. Harrington has spent many years in service to the optical community primarily through his professional association with SPIE, The International Society for Optical Engineering and through his work as a science advisor to the US Department of State. As member of SPIE’s leadership and in 2002 as President of SPIE he traveled extensively promoting optics research and education. He has met with many leaders in the US, Europe, and the far East to help arrange professional society meetings that promote not only many technical areas involving the broad field of optics but also to encourage many students to participate in professional conferences. Through his chairmanship of the US Advisory Committee of the International Commission on Optics (USAC/ICO), he has been very involved in working with a team of dedicated optics professionals to promote optics and photonics on a national level. During the 2005-2006, Dr. Harrington was a Jefferson Science Fellow at the US Department of State. He worked as a science advisor within the Bureau of International Security and Nonproliferation, Office of Conventional Arms and Threat Reduction (ISN/SATR) where he assisted in the establishment of controls for dual-use high technology goods. Specifically, his work with State, the Departments of Defense, Commerce, and the 40 nations making up the Wassenaar Arrangement helped establish controls for lasers and for low-light level sensors and cameras. His interests include control of dual-use technology, non-immigrant visas, and the application of non-life science and engineering solutions to improve the standard of living in less developed countries.

Senior Electro-Optical Engineer. Lightfleet. Lightfleet is an emerging early staged Pre-IPO growth company that has invented the world's first free-space broadcast optical interconnect. Simply put, Lightfleet has created a new way for computers to communicate using light instead of wires. Lightfleet's CorowaveTM technology streamlines computer-to-computer communication by empowering computers to directly talk to each other over short distances through the air with broadcast light. Why is this important? The biggest technology revolution in the way we work, learn, play, and interact with the world has just begun. The growing tidal wave of demand for digital data is unprecedented and will continue to grow geometrically in size for many years to come.
