Optically controlled phased array antenna from X-band to terahertz

In the nineteen eighties and the early nineties microwave photonics was dominated by research related to the optically fed and controlled phased array antenna. By virtue of the fact that terahertz falls in between high speed electronics (mm-wave electronics) and photonics, the extension of microwave photonics, particularly for phased array applications represents a new challenging opportunity. The possibility of an optically fed terahertz antenna will be discussed.
