“…High‐performance phase‐noise measurement is indispensable for designing and fabricating low phase‐noise microwave sources that are essential in virtually all electronic systems. By introducing a long time delay in the optical domain and performing optical mixing between the original and the delayed signals, the phase information can be extracted.…”

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.

“…Figure 9 shows the measured phase noise. Phase noise measurement system has already been proposed based on MPSs incorporating with an ODL [13,[28][29]. However, the working bandwidth of the proposed systems is limited by transition bandwidth of an OBPF and the ODL in these approaches will induce some extra noise.…”

“…Phase noise of the microwave signals with a low frequency cannot be precisely characterized. In [29], the phase shifter is based on the system in [22] and it is difficult to use in the realistic applications. For some applications, it is more desirable to effectively expand the phase noise measurement range out to Nyquist frequency to totally reveal phase noise performance.…”

We demonstrate a photonic-assisted wideband phase noise analyzer based on optoelectronic hybrid units comprising a microwave photonic phase shifter (MPS) and a microwave true time delayer. The MPS and the microwave true time delayer are achieved by a dual-drive Mach-Zehnder modulator (DMZM) incorporating with a broadband microwave frequency up-convertor (MFC) and an optical fiber delay line (ODL), respectively. Our scheme, which is analogous to the conventional microwave delayed homodyne self-reference method, can effectively improve its accuracy using longer time delay with minimum power consumption. In the scheme, the microwave signal is up-converted using the MFC and then down-converted using optical mixing in a photo-detector (PD). Meanwhile, the microwave signal is phase shifted using the MPS and time delayed using the ODL and are finally homodyne mixed with reference signals for converting phase fluctuations to voltage fluctuations. The motivation of this work lies in the fact that the previously reported phase noise measurement configurations based on photonic techniques are hard to accurately measure phase noise of microwave oscillators working at low frequencies. The microwave signals are phase tuned over 360º at frequency range of 0.5-9 GHz to achieve a photonic-assisted phase detector. Microwave signals at the frequency of 3-, 9-GHz are measured with a phase noise of -70.9 and -66 dBc/Hz at 1 kHz offset frequency, respectively.Index Terms-Phase noise measurement, microwave photonic phase shifter, microwave frequency up-conversion.

“…The main problem with such phase noise measurement systems is that the operation bandwidth is usually limited by the electrical devices such as the electrical amplifiers and mixers. Recently, a wideband phase noise measurement scheme using a multifunctional microwave photonic processor was proposed, in which the microwave photonic processor realizes the functions of electrical-to-optical conversion, time delaying, and phase shifting of the delayed signal [7]. However, the frequency mixing is performed in the electrical domain, which still restricts the operational bandwidth.…”

An approach for phase noise measurement of microwave signal sources based on a microwave photonic frequency down-converter is proposed. Using the same optical carrier, the microwave signal under test is applied to generate two +1st-order optical sidebands by two stages of electro-optical modulations. A time delay is introduced between the two sidebands through a span of fiber. By beating the two +1st-order sidebands at a photodetector, frequency down-conversion is implemented, and phase noise of the signal under test can be calculated thereafter. The system has a very large operation bandwidth thanks to the frequency conversion in the optical domain, and good phase noise measurement sensitivity can be achieved since the signal degradation caused by electrical amplifiers is avoided. An experiment is carried out. The phase noise measured by the proposed system agrees well with that measured by a commercial spectrum analyzer or provided by the datasheet. A large operation bandwidth of 5-40 GHz is demonstrated using the proposed system. Moreover, good phase noise floor is achieved (-123 dBc/Hz at 1 kHz and -137 dBc/Hz at 10 kHz at 10 GHz), which is nearly constant over the full measurement range.
