“…Based on the idea of active optical fiber loop, a new PRFM using frequency-shifting recirculating delay line structure was further proposed, which had overcome the lasing problem of the fiber loop. The structure stored 390 MHz-5 GHz, 200 ns RF pulse signals with a maximum storage time of 300 µs (186 circulations), which initially verified the high-fidelity storage of broadband RF signals [15,16]. In order to extend the bandwidth and add the velocity deception jamming mode, we proposed a photonic high-fidelity storage structure of broadband RF signals with Doppler frequency shift (DFS), which achieved high-fidelity storage of 4 GHz-12 GHz RF pulse signals and realized joint jamming of range and velocity.…”

“…In order to solve the conflict between IBW, fidelity and response time, photonic RF memory (PRFM) has attracted much attention with many outstanding advantages [12,13]. First, an active optical fiber loop based RF storage structure was proposed, and the feasibility of PRFM was verified by theoretical simulation [14]. The structure of the active optical fiber loop could flexibly select the storage time and the number of stored RF pulses, which had obvious advantage in terms of storing broadband RF pulses.…”

A multifunctional photonic broadband RF memory structure is presented to adapt to more and more complex electronic jamming scenarios. Based on precise sequence control of the structure with integration of switching and amplification functions at the output end, the response time of the structure is greatly reduced to 30 ns. Moreover, multiple jamming modes including reconfiguration of Doppler frequency shift (DFS), instantaneous bandwidth (IBW), center frequency, pulse width, storage time and pulse number are realized based on a coherent DFS structure with tunable optical filter and a memory structure with Vernier effect. The tuning range of DFS is greater than ±9 MHz, the reconfiguration range of IBW is 1.5 GHz–11 GHz, the tuning range of center frequency is 6.5 GHz–17 GHz, the maximum storage time of 100 ns–10 µs RF pulse signals is 750 µs, and the maximum number of stored RF pulses is 2500.

“…Figure 4 shows the structure of a new PRFM that can realise a long storage time, wide IBW and high dynamic range [11]. The concept is based on the use of an optical frequency shifter inside a recirculating delay line loop to overcome the lasing problem and to enable multiple recirculations and long storage time to be realised.…”

Microwave photonics merges the worlds of RF and photonics to enable new paradigms in the processing of high speed signals. Besides its inherent advantages of extremely high time-bandwidth product and natural immunity to electromagnetic interference, a fundamental benefit of photonic techniques for processing wideband electromagnetic systems is that the entire RF/mm-wave spectrum constitutes only a small fraction of the carrier optical frequency. This enables dynamic reconfiguration of the processor characteristics over multi-GHz bandwidths, and offers the ability to realise functions in microwave systems that are either very complex or, perhaps not even possible in the RF domain. This paper describes recent new advances in microwave photonic signal processors including ultra-wideband optically controlled phased array beamforming; widely tunable and switchable filters; wideband frequency converters; high-resolution multiple frequency microwave photonic measurement systems; and photonic RF memory structures.

“…In 2003, Linh VT Nguyen first proposed the RF memory structure based on active fiber loop [11] , and carried out a theoretical simulation analysis, which initially verified the feasibility of the method and pointed out the key problems to be solved in the structure. In 2014, an all-optical RF memory structure based on frequency shift recirculating delay line was proposed [12] . This structure effectively overcomes the deterioration of replication times caused by coherent lasing and rapid noise accumulation in fiber loop.…”

In order to overcome the bottleneck of digital radio-frequency (RF) memory such as narrow instantaneous bandwidth and low analogue-digital conversion rate, photonic RF memory technology with broad instantaneous bandwidth and fast response capability has been developed. In this paper, RF memory structure based on active recirculating loop with depth and high stable signal-to-noise ratio(SNR) is proposed and experimentally verified, which can meet the requirements of bandwidth and response speed in current RF storage field. This structure combines the active optical switch with the fiber delay-loop-based structure, which greatly increases the storage duration, suppresses out-of-pulse noise and improves the SNR while ensuring the ultralow loss of the photonic loop. The structure realizes RF storage with real-time response in 2- 18GHz frequency spectrum and pulse replication times is more than 360(equal to 18μs delay time), the average level of SNR is 20dB and its fluctuation over time is less than 1.5dB, which can be applied to different applications where broad transient bandwidth storage with long time delay is needed.
