Abstract

Delay effects Delay lines EMP radiation effects Microwave frequencies Optical fiber devices Optical fibers Optical pulses Pulse amplifiers Radio frequency Switches
The use of optical fibers as the delay line elements in high-frequency memory loops provides light-weight and small-size devices with long time delays. The authors present a performance analysis and experimental results on a 2-6 GHz fiber-optic recirculating delay line. It is shown that microseconds delays can be achieved using the fiber-optic memory loop (FOML) in the 2 to 6 GHz band. The main advantages of the FOML devices are long delay times, in excess of 100 mu s, a reduction in weight and size by an order of magnitude or more, and immunity to interference (electromagnetic interference and electromagnetic pulse).< >
