Book Description
The focus of this thesis is to investigate the implementation of Radio Frequency (RF) In-Phase and Quadrature-Phase (I/Q) vector modulation through the use of modern photonic components and sub-systems which offer extremely wide RF intrinsic bandwidths. All-electronic vector modulators suffer from frequency coverage limitations and amplitude and phase instability due to components such as phase shifters and variable gain controllers operating at or near 100\% bandwidth. In stark contrast, once an RF signal has been modulated onto an optical carrier, the percent bandwidth of the RF to carrier is typically less than 0.01\% percent. The fundamental mechanisms and basic electronic and photonic components needed to achieve vector modulation is introduced first. The primary electrical component required in most architectures is the 90° RF hybrid coupler, which is required to generate the RF I and Q terms. The two primary photonic building blocks, aside from the laser, electro-optic modulator and demodulator, are Mach-Zehnder Modulators (MZM) and Variable Optical Attenuators (VOA). Through the utilization of these components, multiple past architectures are explored and multiple new architectures are designed simulated. For each architecture, there is a discussion on the practical implementation. Considerations such as system complexity, integration, and sensitivity to unwanted environmental stimuli are taken into account with potential solutions to alleviate these risks. In closing, the noise figure and its impact on Spur-Free Dynamic Range (SFDR) for a basic RF photonic link is derived to provide a system-level figure of merit that can be used, in most RF applications, to determine the overall performance utility current and future designs.

Book Description
In this book we present a snapshot of the state of the art in photonics in 1994, showing typical applications and emerging new ones; discussing the key technologies behind these applications, their limitations, and prospects. The articles in this book are extended versions of the papers presented at the first International Conference on Applications ofPhotonic Technology (ICAPT'94), held in Toronto, Canada, on June 21-23, 1994. Photonics has been recognized as one of the key technologies for the 21 st century, as electronics was the technology of the 20th centrury and electrical engineering changed the life of people in the 19th century. According to the recent report of the Organization for Economic Cooperation and Development in Paris (OECD), the market for photonics will grow dramatically in the next 10 years with an expected world-wide expenditure of US $230 billion from some US $30 billion in 1992. The explosion of information technology was the largest driving force for the deployment of photonic technology. It created insatiable demand for ever-higher data transmission and processing rates, which cannot be sustained by electronics alone. Boosted by the enonnous investment of the telecommunications and defense industries, the demand for photonics (or optoelectronics) is steadily increasing. It is solidly established in the long haul communications, laser printers and CD-ROMs.

Book Description
The potential of photonic signal processing (PSP) to overcome electronic limits for processing ultra-wideband signals, provide signal conditioning that can be integrated in line with fiber optic systems, and improve signal quality makes this technology extremely attractive for improvement in receiver sensitivity performance. Spanning the current transitional period, Photonic Signal Processing: Techniques and Applications addresses the merging techniques of processing and manipulating signals propagating in the optical domain. The book begins with a historical perspective of PSP and introduces photonic components essential for photonic processing systems, such as optical amplification devices, optical fibers, and optical modulators. The author demonstrates the representation of photonic circuits via a signal flow graph technique adapted for photonic domain. He describes photonic signal processors, such as differentiators and integrators, and their applications for the generation of solitons, and then covers the application of these solitons in optically amplified fiber transmission systems. The book illustrates the compensation dispersion using a photonic processor, the design of optical filters using photonic processor techniques, and the filtering of microwave signals in the optical domain. Exploring methods for the processing of signals in the optical domain, the book includes solutions to photonic circuits that use signal flow techniques and significant applications in short pulse generation, the filtering of signals, differentiation, and the integration of signals. It delineates fundamental techniques on the processing of signals in the optical domain as well as their applications that lead to advanced aspects of performing generation of short pulses, integration, differentiation, and filtering for optical communications systems and networks and processing of ultra-high speed signals.

Book Description
This lecture focuses on the applications of RF photonics for array antennas in signal distribution, beamforming, beam control, and antenna remoting. Examples are given to discuss the requirements, benefits, and design approaches of photonics for phased array antennas. The first demonstration of using photonics for a dual band array was conducted in 1990. Later a wide band conformal array controlled by photonics was built and tested. This example talks about the optical control of phased arrays by using fiber-optic links for RF and data remoting and a time-shifi beamforming network for wide instantaneous bandwidth. Last, the talk will illustrate how photonics can be used to form a wide band feed system for multibeam arrays.
