“…Moreover, this first implementation brought out the main technological issues of silicon photonics that will drive further developments of hybrid integrated photonics platforms. In a dual way, the same microwave photonic solution can allow to implement in the optical domain a down conversion of a received RF signal to intermediate frequency, resulting in an ultra wideband tunable RF receveir [39].…”

In the last decade, the interest in software-defined ultra-wideband (UWB) and tunable radio frequency (RF) apparatuses with low size, weight, and power consumption (SWaP), has grown dramatically, pushed by the new 6G vision where, RF equipment shall enable a large number of fundamental applications as UWB communications, robot localization mapping and control and high precision radars, all of them contributing in revolutionizing our life style. Unfortunately, the coexistence of ultra-wideband and software-defined operation, tunability and low SWaP represents a big issue in the current RF technologies. In this article, to the best of our knowledge, the first example of a complete tunable software-defined RF transmitter with low footprint (i.e. on photonic chip) is presented exceeding the state-of-the-art for the extremely large tunability range of 0.5-50 GHz without any parallelization of narrower-band components and with fast tuning (<200micros). This first implementation, represents a breakthrough in microwave photonics.

“…Photonics-based frequency scanning is another effective method for spectrum sensing, which follows the concept of frequency scanning receiver in the electrical domain and can be realized by sweeping the frequency of a photonic LO [39]- [42], an optically carried RF signal [43]- [46], or the response of an optical filter [47]- [49]. Table III compares the performances of the spectrum sensing based on different methods in this category.…”

Cognitive radio is considered as a possible disruptive force to improve the spectral resource efficiency through sensing and interacting with the environment. Traditional electrical technologies to implement the cognitive radio face challenges in terms of bandwidth, resolution, and speed. In this paper, the concept and architecture of broadband cognitive radio systems enabled by photonics are proposed. Key microwave photonic techniques for the architecture are reviewed, including the photonics-based spectrum sensing, the photonic arbitrary waveform generation, the photonics-based self-interference cancellation processing, and the microwave photonic dechirp processing and radar imaging. A preliminary demonstration of a cognitive radar system enabled by photonics is performed. The future possible research directions on this topic are discussed.

“…Due to the prominent merits of low loss in long haul transmission, immunity to electromagnetic interference, and potential for integration and flexible tunability, the photonic radiofrequency (RF) receiver has been considered as a promising technique for processing broadband RF signals, which can be applied in a wide range of applications such as wireless communication systems, electronic warfares, radio astronomy, and radars. [1][2][3] In these years, as the key component of the photonic RF receiver, a variety of photonic downconversion mixers have been therefore proposed. In References 4-6, RF signals and local oscillation (LO) signals were separately introduced into different kinds of modulators such as intensity modulators, phase modulators (PMs), and polarization modulators, and the photonic mixing has been achieved via photodetectors (PDs).…”

A photonic radiofrequency (RF) receiver utilizing a phase modulator (PM) and a tunable single sideband (SSB) optoelectronic oscillator (OEO) is proposed and experimentally demonstrated. In this scheme, the RF signal to be detected is modulated on the PM in one optical path, while a local oscillation (LO) signal is optically generated by the SSB OEO in the other optical path. After combining two paths of optical signals via an optical coupler, an immediate frequency (IF) signal is obtained by photonic RF downconversion in a photodetector (PD). Through scanning the LO signal and monitoring the IF signal simultaneously, the input unknown RF signal can be detected. In the experiment, the RF tones with the operating frequency from 8.1 to 12.1 GHz are successfully detected. The minimum detectable RF power at 10.1 GHz is −84.6 dBm, and the spurious free dynamic range of the photonic RF receiver measured is about 73.8 dB/Hz2/3.
