Paper Abstract

A method to generate and control one or a set of time delays using fiber optic cavities is described. The time delays can be finely controlled over a continuum resulting from a change in the voltage of a single control signal. Architectures using these devices for controlling transmitting and receiving RF arrays are described. The controller can scan an RF array beam rapidly over a continuum of angles. Issues addressed in this paper include the relationship between design parameters of the device and maximum delay achievable, signal attenuation versus delay, and uncertainty in delay, and the switching speed of the RF array beam pointing direction.
