Abstract

Ultrafast switching utilizing picosecond photoconductors finds many applications, including optoelectronic sampling and characterization of high-speed electronic devices [l]. A major area of application that has not been explored is in microwave and millimeter- wave generation and control. The low-noise switching characteristic of these devices is very promising, since the microwave or millimeter wave signals can be generated in complete time synchronization with the exciting optical pulses. The time synchronization opens the door to unique applications. For example, it becomes possible to use optoelectronic techniques to modulate the CW microwave signal, allowing high data-rate signaling. Another potentially powerful application is in phased array antennas, where the central issue is to provide the correct phase and amplitude at each element of the array in a manner which allows rapid scanning.
