Multichannel and Multirate All-Optical Clock Recovery
Thu, Jul 06, 2006 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
SPEAKER: Prof. Franko Kueppers, University of ArizonaABSTRACT: Clock recovery (CR) is a fundamental operation in digital transmission systems, including optical telecommunications. Today it is performed in the electrical domain, but in recent years considerable effort has been made to find optical alternatives which have been proven substantially faster than available electrical ones. Since the optical fiber in a dense wavelength-division-multiplexing (DWDM) system hosts multiple wavelength channels, it is desirable to extend this parallelism to signal processing by finding means of all-optical CR. However, most of the proposed schemes work only for one wavelength channel (and one data rate) at a time and demonstrations of parallel operation (two and four wavelength channels) have remained few.In my talk I will present a new all-optical CR scheme based on a simple device consisting of a birefringent resonator and a polarizer. The concept was demonstrated for 21 simultaneous channels, 20 carrying data at 10 Gbit/s and one at 40 Gbit/s. The scheme is fully passive and could be extended to data rates of 100/160 Gbit/s and over the entire C- and L-bands, bringing the number of processed channels up to 40 or more.BIO: Franko Kueppers is an Assistant Professor at the College of Optical Sciences at the University of Arizona in Tucson, where he represents the field of Photonic Telecommunication Systems. He holds degrees in Electrical (B.Sc.), Communications (M.Sc.), and Optical Communications (Ph.D.) Engineering from various German Universities. He has been with Siemens and spent ten years in the telecommunications industry at the Technology Center of the world's largest telecommunications network operator, Deutsche Telekom. As a Head of the Photonic Systems Department he was responsible for national and international projects on scientific, engineering, and techno-economical aspects of transmission systems and optical networks. He is one of the architects of Deutsche Telekom's first WDM transport platform, he and his team conducted the world's first 40 Gbit/s commercial and 160 Gbit/s experimental field trials, he has more than 40 publications including patents, articles in scientific journals, invited presentations at conferences like OFC and ECOC, and he is a co-author of the Springer "Handbook of Telecommunications."HOST: Prof. Alan Willner, willner@usc.edu

An Image Transceiver-Based, Low Vision Goggle: Research Progress
Wed, Jul 26, 2006 @ 02:30 PM - 03:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Uzi Efron, Dept. of Electro-Optical Engineering, Ben-Gurion University, Beer-Sheva, Israel, Dept. of Electrical Engineering, Holon Institute of Technology, Holon, IsraelAbstract:A mobile, Head-Mounted Low Vision Aid is critically needed for the vision impaired. We will report on a research effort centered around a unique Image Transceiver Device (ITD), combining both functions of imaging and display in a single CMOS chip. The device will allow a compact design of a Head-Mounted Goggle in which the imager part will capture the input imagery. Following the processing of the latter by a wearable computer, the processed imagery will be generated by the display part of the device and re-routed using appropriate optics, to the healthy part of the subject's retina. The present design of the ITD Device is based on a CMOS LCOS micro-display and an APS imager technology, in which the front side LCD and the back-illuminated imager are integrated in a single silicon substrate. The device design effort includes the chip as well as the FPGA system controller.
In addition to the ITD Chip development the research effort also includes:(a) The optical design of the Low Vision Goggle;(b) The development of a Low Vision model;(c) Studies of Image Processing/enhancement Algorithms for the visually impaired. A detailed discussion of all these research areas will be presented.Host: Dr. Keith Jenkins, x04149, jenkins@sipi.usc.edu
