PHOTONICS AND INTEGRATED SYSTEMS SEMINAR
Thu, Jan 12, 2012 @ 03:30 PM - 04:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Willie Ng, HRL Laboratories
Talk Title: Photonics for Microwave Systems and
Abstract: This seminar will describe the development and utilization of photonics technologies in microwave antenna systems and ultra-wideband signal processing. It will cover our recent work on photonic assisted analog-to-digital conversion, the characterization of jitter in mode-locked lasers, frequency-locked photonic oscillators, and the use of Si microdisk heterogeneously integrated with silica waveguides for RF-photonic filtering. In addition, it will also describe how the broadband capabilities of photonics and wavelength division multiplexed (WDM) technologies can be exploited for high dynamic range antenna remoting and true-time-delay beamforming that cover multiple microwave bands.
Biography: Dr. Willie Ng is currently a Principal Research Scientist at HRL Laboratories, Malibu, CA, a research and development company jointly owned by Boeing and General Motors. He has led the photonics effort at HRL since 1997. Under DARPA and Air Force sponsorships, he has led HRL teams that demonstrated a variety of photonic devices/subsystems designed for microwave antenna systems and ultra-wideband signal processing, including RF-photonic filtering and photonics-assisted analog-to-digital conversion. He has given many invited talks in IEEE/OSA Conferences and DARPA Symposiums, and is the author and co-author of over 100 journal articles and conference papers. He holds 20 U.S. patents in the area of photonics technology, with many pending. Cited for pioneering contributions to microwave photonics, he was one of six individuals selected to receive the Excellence in Technology Award in 2005 from the Raytheon Company. Prior to HRL, he was a Member of the Technical Staff in the Rockwell Science Center, Thousand Oaks, Calif. In the Optoelectronics Group of Dr. D. Dapkus, he developed GaInAsP/InP buried heterostructure lasers and power converters. He received his B.S. degree in Electrical Engineering from Case Western Reserve University (Cleveland, Ohio), and his M.S. and Ph.D. degrees in Electrical Engineering from the California Institute of Technology (Pasadena, Calif.) under the guidance of Prof. A. Yariv. His thesis work was on the demonstration of GaAlAs/GaAs Distributed Bragg Reflector lasers and Bragg waveguides. He is a fellow of the IEEE (Class of 2010).
