“…A microwave channelizer is a device that is able to slice the spectrum of a microwave signal into a bank of narrow channels and each channel provides a high‐resolution and high‐sensitivity measurement for a channel bandwidth in this channel. Currently, photonic‐assisted microwave channelizers have been developed based on space‐division multiplexing (SDM) , wavelength‐division multiplexing (WDM) , and time‐division multiplexing (TDM) .…”

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.

“…Second, channelization of broad-band signals and translation into a common IF can greatly reduce the requirement and cost of post-processing electronics. Various embodiments of optical processor architectures have been proposed and demonstrated [1]- [8]. Acoustooptic (AO) systems have been built that are either incoherent [1], producing a power spectrum of the input signal, or coherent [2], [3], in which the output preserves both the amplitude and phase of the input signal.…”

A coherent optical RF channelizer has been constructed and characterized. The optical channelizer is based on a free-space optical diffraction grating, and utilizes coherent optical heterodyne detection to translate all of the frequency channels to a common intermediate frequency (IF). The designed optical channelizer has a 1-GHz channel spacing, and a nominal 5-GHz IF, and can offer an instantaneous bandwidth greater than 100 GHz. The channelizing receiver has been characterized for its frequency response, crosstalk, and spur-free dynamic range, and the results are in a good agreement with the theoretical values.

“…Optical comb filters or fiber gratings are used to process the sidebands induced by modulating continuous-wave (CW) lasers with a coming signal and the frequency to be measured can be estimated from the optical power of the sidebands filtered [16]- [21]. Optical channelizers consisting of or a phased array of waveguide delay lines, fiber Bragg gratings array, free-space optical diffraction grating, or Fabry-Perot etalon and incoherent source, have been proposed [22]- [27]. The optical mixing can be performed by cascaded external modulators, signal re-modulation, or four-wave mixing in semiconductor optical amplifier (SOA) and highly nonlinear fiber [28]- [30].…”

Abstract-A photonic approach with multiple free spectral ranges (FSRs) is proposed to perform instantaneous frequency measurement. In the proposed approach, multiple channels are firstly designed with the use of multiple laser sources operating at different wavelengths and a comb filter, leading to the generation of multiple FSRs at these channels. The microwave signal with its frequency to be measured is imposed on these channels. After passing through the comb filter, optical powers at the outputs of the multiple channels are then detected and processed to estimate the frequency, with multiple FSRs or multiple measurement ranges derived during the measurement process. Such an approach is demonstrated by an experimental setup where two channels operating at 1520nm and 1550nm and a delay line interferometer based comb filter are implemented to get two different FSRs. Within the range of 12~35GHz, the measured frequencies are in a good agreement with the input frequencies being measured.
