Special Issue Information

Dear Colleagues,

The field of microwave photonics (MWP) focuses on the interaction between light wave and electrical wave, and has been developed for studying the generation, processing, and distribution of microwave signals by means of photonics. Over the past several decades, the field of microwave photonics has been continuously growing and expanding. Extensive research activities throughout the world lead to many excellent research findings, such as the development of microwave photonic devices, systems, and networks. In addition to microwave systems using discrete components, recent developments have also demonstrated the success of integrated microwave photonics, which may enable better performance in size, stability, cost, etc. Therefore, we invite potential authors to contribute their new insights in this exciting and fast-growing field of microwave photonics.

This Special Issue of Photonics, entitled Signal processing and transmission enabled by Microwave Photonics, is to highlight the recent progress and trends in the research of microwave photonics. Both original research papers and review articles are welcome in this Special Issue. Technical topics include, but are not limited to, the following:

  • MWP signal generation;
  • MWP signal processing;
  • Radio over fiber transmission;
  • MWP techniques for 5G/6G;
  • Integrated microwave photonics;
  • MWP signal recognition;
  • MWP sensing technology;
  • Development of MWP devices, components, and systems.

Contributing papers need to present original, unpublished work and will be subjected to a peer-reviewed process to assure meeting the quality standard of the journal. Submitted manuscripts must be prepared according to the author guidelines of Photonics and uploaded through to the MDPI electronic submission system.

In this paper, a photonic-enabled image rejection mixer (IRM) that features an ultrawideband self-interference cancellation (SIC) function and a compact configuration is proposed. The parameter tuning of SIC is realized in an optical domain, which avoids the use of electrically tuned devices with limited bandwidth and precision, so that high-precision parameter matching can be realized in the optical domain to realize deep and ultrawideband SIC. The key point of image rejection (IR) is to construct a pair of orthogonal local oscillation (LO) signals through DC-bias-induced phase shift. This not only avoids a high-frequency electrical 90-degree hybrid coupler (HC) applied in the traditional Hartley structure, but also compensates the phase deviation in the electrical intermediate frequency (IF) 90-degree HC flexibly, ensuring wideband and deep IR operation. The simulation results show that the proposed IRM can achieve ultrawideband SIC and IR with the simultaneous high-efficiency recovery of useful signals. They also verify that the scheme has good resistance to strong interference, and can cope with the phase imbalance of the IF 90-degree electrical HC, ensuring the good performance of the system, which has a wide application prospect in various in-band full-duplex (IBFD) systems.

We have demonstrated a Rydberg atom-based two-band communication with the optically excited Rydberg state coupled to another pair of Rydberg states by two microwave fields, respectively. The initial Rydberg state is excited by a three-color electromagnetically-induced absorption in rubidium vapor cell via cascading transitions, with all of them located in infrared bands: a 780 nm laser servers as a probe to monitor the optical transmittancy via transition 5S1/2→5P3/2, 776 nm and 1260 nm lasers are used to couple the states 5P3/2 and 5D5/2 and states 5D5/2 and 44F7/2. Experimentally, we show that two channel communications carried on the two microwave transitions influence each other irreconcilably, so that they cannot work at their most sensitive microwave-optical conversion points simultaneously. For a remarkable communication quality for both channels, the two microwave fields both have to make concessions to reach a common microwave-optical gain. The optimized balance for the two microwave intensities locates at EMW1=6.5 mV/cm and EMW2=5.5 mV/cm in our case. This mutual exclusive influence is theoretically well-explained by an optical Bloch equation considering all optical and microwave field interactions with atoms. Full article
