“…Based on the results shown in Figures 8, 9, the proposed channelized receiver can provide a much larger operative bandwidth by using the same number of devices when compared with the existing works in [23,[26][27][28][29][30][31][32]. Using two OHs, four BPDs, two EQHs, and four electrical LPFs, the equivalent operative bandwidth of the proposed multi-band channelized receiver can be up to 28 GHz.…”

“…Most of the initial coherent channelized receivers [23,[26][27][28][29][30][31][32] were designed for fixed microwave bands, where the spectrum information must be known in advance. Those coherent channelized receivers can only work for specific microwave bands.…”

“…192.885 THz. It is worth mentioning that CWs used in U-FOCG 1 and U-FOCG 2 should be generated from the same optical laser source [23,[27][28][29][30][31]. For the dynamic 4 GHz signal with microwave bands between 2 GHz and 30 GHz, the relationship among CFs of the OCs, v-copies, CFs of the LOs, and the channelized sub-signals is clearly shown in Table 3.…”

“…Recent approaches to photonics-assisted coherent channelization without optical filters have also been demonstrated [11,23,[26][27][28][29][30]. This channelization scheme, i.e., the third photonic channelization category demands no optical filters, but it requires a couple of coherent comb light sources with detuning comb line spacing [23,30].…”

Due to the limitation of analog-to-digital/digital-to-analog converters, photonics-assisted channelized receivers are thought to be a promising approach to receiving wideband microwave signals. Herein, based on the spectrum analysis and the coherent channelization, we develop a photonics-assisted channelized receiver for multi-band microwave signals. In the proposed channelized receiver, the instantaneous spectral analysis is introduced to determine the frequencies and bandwidth of a dynamic wideband signal. The dynamic wideband signal is then received by a multi-band coherent channelizer. By exploiting transparency of the optoelectronic devices, we equivalently build a multi-band coherent channelizer that can work for dynamic microwave signals, where a few optoelectronic devices are required. Compared with the existing coherent channelizers, the operative bandwidth of the proposed multi-band coherent channelizer is much larger (up to 28 GHz). The proposed photonics-assisted channelized receiver doesn't need tunable optical comb generators and radio frequency sources, and it also doesn't require knowing the spectrum information in advance. Moreover, the designed example of the proposed photonics-assisted channelized receiver for a 4 GHz original signal in 2-30 GHz microwave bands is given and discussed. The spectrum information of the dynamic original signals is obtained by monitoring the optical power in each sub-channel. We verify the feasibility of the multi-band coherent channelizer by channelizing two 4 GHz linearly-chirped signals with center frequencies of 4 and 28 GHz into four 1 GHz sub-channels, respectively.

“…Conversely, an OBFN requires a dynamic MCL, which nonetheless must be kept simple, scalable and fast just enough to track phase drifting, in order to be suitable for a large-scale OBFN. While all stages of a photonic-aided payload have been individually validated—modulation 6,12–16 , beamforming 9,10,17–21 , frequency conversion 22,23 and coherent detection 6,9,24 —such an MCL has never been demonstrated, preventing the demonstration of a scalable, modular and coherent photonic-aided payload.…”

Modular coherent photonic-aided payload receiver for communications satellites

Ubiquitous satellite communications are in a leading position for bridging the digital divide. Fulfilling such a mission will require satellite services on par with fibre services, both in bandwidth and cost. Achieving such a performance requires a new generation of communications payloads powered by large-scale processors, enabling a dynamic allocation of hundreds of beams with a total capacity beyond 1 Tbit s −1 . The fact that the scale of the processor is proportional to the wavelength of its signals has made photonics a key technology for its implementation. However, one last challenge hinders the introduction of photonics: while large-scale processors demand a modular implementation, coherency among signals must be preserved using simple methods. Here, we demonstrate a coherent photonic-aided receiver meeting such demands. This work shows that a modular and coherent photonic-aided payload is feasible, making way to an extensive introduction of photonics in next generation communications satellites.

As an emerging topic, photonic-assisted microwave measurements with distinct features such as wide frequency coverage, large instantaneous bandwidth, low frequencydependent loss, and immunity to electromagnetic interference, have been extensively studied recently. In this article, we provide a comprehensive overview of the latest advances in photonic microwave measurements, including microwave spectrum analysis, instantaneous frequency measurement, microwave channelization, Doppler frequency-shift measurement, angle-of-arrival detection, time-frequency analysis, compressive sensing, and phase-noise measurement. A photonic microwave radar, as a functional measurement system, is also reviewed. The performance of the photonic measurement solutions is evaluated and compared with the electronic solutions. Future prospects using photonic integrated circuits and software-defined architectures to further improve the measurement performance are also discussed.
