RF PHOTONIC TECHNOLOGY IN OPTICAL
FIBER LINKS
In many applications, radio-frequency (RF) signals need to be transmitted and pro-
cessed without being digitalized. These analog applications include CATV, antenna
remoting, phased array antenna and radar amongst others. Optical fiber provides
a transmission medium in which RF modulated optical carriers can be transmitted
and distributed with very low loss. With modulation and demodulation of the opti-
cal carrier at the sending and receiving ends, the optical fiber system functions like
a low-loss analog RF transmission, distribution, and signal processing system. RF
photonic fiber technology has particular advantages in that it is more efficient, less
complex,and less costly than conventional electronic systems, especially at high mi-
crowave and millimeter wave frequencies. Analog signal processing of RF signals
can be achieved optically while the signal is being transmitted along the optical car-
rier. Examples of such processing techniques include up- and down-conversion of
RF frequencies, true time delay of RF signals, and optical distribution of RF clocks.
This volume presents a review of RF photonic components, transmission sys-
tems, and signal processing examples in optical fibers from the leading academic,
government, and industry scientists working in this field. It discusses important
concepts such as RF efficiency, nonlinear distortion, spurious free dynamic range,
and noise figures. This is followed by an introduction to various related technolo-
gies such as direct modulation of laser sources, external modulation techniques
(including lithium niobate modulators, polymer modulators and semiconductor
electroabsorption modulators), and detectors. In addition, several examples of RF
photonic signal processing technology, such as the phased array, the optoelectronic
oscillator, and up and down RF frequency conversion and mixing, are presented.
These will stimulate new ideas for applications in RF photonic signal processing.
RF Photonic Technology in Optical Fiber Links will be a valuable reference
source for professionals and academics engaged in the research and development
of optical fibers and analog RF applications. The text is aimed at engineers and
scientists with a graduate-school education in physics or engineering. With an
emphasis on design, performance, and practical application, this book will be of
particular interest to those developing novel systems based on this technology.
