Paper Abstract

The first microwave-phased array antenna steered by optical delay lines is described. The optical ''time shifters'' utilize the propagation of light waves through a finite length of fiber to generate the time delays that control the beam pointing angle. Delay times specified by the antenna steering angle were implemented by switching bias currents of high speed lasers pigtailed to fiber optic delay lines.
