Abstract
A new structure for storing a radio frequency (RF) signal utilising a fibre-optic delay
line is presented. It is based on a frequency shifting recirculating delay line loop for the RF
pulse storage, which prevents lasing and enables multiple recirculations and long storage time to
be realised. The new photonic RF memory (PRFM) can realise a long reconfigurable storage time,
wide instantaneous bandwidth and high dynamic range. Experimental demonstration of the frequency
shifting loop based PRFM has been carried out for the first time, showing a long and
reconfigurable storage time of more than 300 μs with high signal fidelity.
