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.

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 use of photonics for phased-array applications has been discussed for quite some time. Main difficulties up to now have been the component count and cost for relatively complex systems. The advances in photonic integration are very promising to bring down both, as well as reduce volume and weight of phased-array beamforming networks as compared to their electrical counterparts. In addition, photonics allows for increased functionality for wide-bandwidth systems. This paper reports on these advances and indicates the strategy to applicable photonic phased-arrays.
