Ultra-high Frequency Linear Fiber Optic Systems (eBook, PDF)

• Format: PDF

Produktbeschreibung

This book provides an in-depth treatment of both linear fiber-optic systems and their key enabling devices. It presents a concise but rigorous treatment of the theory and practice of analog (linear) fiber-optics links and systems that constitute the foundation of Hybrid Fiber Coax infrastructure in present-day CATV distribution and cable modem Internet access. Emerging applications in remote fiber-optic feed for free-space millimeter wave enterprise campus networks are also described. Issues such as dispersion and interferometric noise are treated quantitatively, and means for mitigating them are explained. This broad but concise text will thus be invaluable not only to students of fiber-optics communication but also to practicing engineers. To the second edition of this book important new aspects of linear fiber-optic transmission technologies are added, such as high level system architectural issues, algorithms for deriving the optimal frequency assignment, directly modulated or externally modulated laser transmitters and the use of Erbium-doped fiber amplifier (EDFA) in linear fiber optic systems. Significant examples of field deployed military systems enabled by linear fiber optic links are described in an appendix.

Autorenporträt

Kam Y. Lau is Professor emeritus in the EECS department at U.C. Berkeley. He received his B.S., M.S.and Ph.D degrees in 1978, 1978 and 1981 respectively; all in Electrical Engineering from Caltech. Upon obtaining his doctorate, he joined Ortel Corporation as founding staff/chief scientist. His research in semiconductor laser dynamics established fundamental limits in speed and linearity of directly modulated laser diodes, which contributed to linear fiber-optic transmission products for Hybrid-Fiber-Coax (HFC) infrastructure widely deployed today for CATV-distribution and cable-modem internet-access - the basis of Ortel's successes - its IPO and subsequent acquisition by Lucent/Agere. He received the 1996 IEEE LEOS William Streifer Scientific Achievement Award, the 1996 IEEE LEOS Distinguished Lecturer Award, the 2008 OSA Nicholas Holonyak Award, the 2009 IEEE David Sarnoff Award and the 2009 IET J.J. Thomson Medal. He was an Associate Professor of Electrical Engineering at Columbia University from 1988-90, and a professor of EECS at U.C. Berkeley since 1990. In 1997, he co-found LGC Wireless, Inc. ("L" of "LGC".) LGC Wireless delivers cost-effective in-building wireless coverage and capacity solutions around the world. LGC Wireless was acquired by ADC Telecom (NASDAQ: ADCT) in 2007. Prof. Lau assumed Emeritus status in 2005.
