Coherent detection for fiber optic networks
Thu, Mar 02, 2006 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Michael G. Taylor, University College LondonAbstract: Years ago coherent detection appeared the best choice for high bit rate receivers in fiber optic communications networks. Then the idea was abruptly discarded after the arrival of the EDFA. Today coherent detection once again offers an attractive solution to many of the issues facing long haul and metro optical transmission. In the latest incarnation real time digital signal processing is used to extract the signal from the coherent mixing products, and it is possible to apply processing in the digital domain to compensate for unlimited amounts of chromatic dispersion and other impairments. The results of experiments will be presented showing how coherent detection is implemented and how it can outperform direct detection in many ways. The flexibility offered by the DSP to modify the optical signal to fit each fiber link has benefits for optical network design, and some of these will be discussed.Bio: Dr. Taylor has 15 years experience in the development of fiber optic transmission products. After completing the Ph.D. degree at University College London in 1990 he joined STL Laboratories (subsequently Nortel) to work on the development of transmission products using optical amplifiers. In 1996 he moved to Ciena Corporation, where he worked on long haul transmission products. He led the development of the 10Gb/s product, and contributed to innovative design features such as the four wave mixing tolerant WDM solution. In 2003 he took an Honorary Senior Lecturer position at University College London, where he began work on new applications for optical coherent detection. He has published over 25 papers and been awarded 14 patents.Host: Professor Alan Willner, willner@usc.edu

hamid.Ghasemi@fhwa.dot.govABSTRACTWith the passage of SAFETEA-LU, the FHWA Office of Infrastructure R&D (HRDI) is initiating the Long-Term Bridge Performance (LTBP) Program, an ambitious multi-year research program which is modeled somewhat after the Long-Term Pavement Performance program. The LTBP Program has been designed as a 20-year effort that will include detailed inspections and periodic evaluations and testing on a representative sample of bridges throughout the United States in order to monitor and document their performance over an extended period of time. The LTBP Program will also include a set of instrumented bridges that can provide continuous, long-term, structural performance data, and may include detailed forensic autopsies on structures that are decommissioned by State transportation agencies. The intent is to collect performance data on deterioration, corrosion, or other types of degradation; structural impacts from overloads; and the effectiveness of various maintenance and improvement strategies typically used throughout the United States. It is anticipated that the resulting LTBP database will provide high quality, quantitative performance data for highway bridges that will support improved designs, improved predictive models, and better bridge management systems in the future. HRDI will be conducting several workshops during 2006 to acquaint FHWA, DOT staff, and researchers on the elements of the program.The Scientific Community is Cordially Invited.Location: Kaprielian Hall (KAP) - rielian Hall, Room 203
