Abstract
A system is described for providing selectable delay. A first converter converts a first electromagnetic signal into an optical signal. An optical switch is coupled to the first converter to provide selectable delay by selection of paths by a plurality of movable microelectromechanical system (MEMS) mirrors. The paths have respective measurable differences in delay for the optical signal. A second converter coupled to the optical switch converts the optical signal into a second electromagnetic signal. The differences in delay for the optical signal result in differences to delay for the second electromagnetic signal in comparison to the first electromagnetic signal. Relatively short delays are provided by the optical switch and relatively long delays are provided by a plurality of fiberoptic delay lines.
