Abstract

A fiber-optic delay network consisting of eight different and selectable fiber delays has been demonstrated over a 1 to 11 GHz frequency range. The delay networks can be used as a three-bit resolution beam steerer for an electronically steered antenna. Discrete delay increments were selected by switching the bias current of high speed 1.3-micron laser diodes pigtailed to the delay lines.
