Abstract

A novel high speed, high on-off ratio (greater than 50 dB) fiber optical shutter switch for optically controlled phased array is proposed. Computer aided design tools for the development of the switch and the phased array have been developed. The beam steering, shaping, and forming are achieved by controlling the on-off status of the fiber shutter switches. The advantages of the phased array antenna using this new device are to possess higher antenna gain, lower sidelobes and higher speed. This fiber optic switch can also be used as fiber optic variable attenuator, isolator, and spatial light modulator for various other applications.
