“…Up to now, many achievements have been reported on the photonic integrated circuits for possible radar applications [400]. In particular, a variety of integrated optical beamformers have been demonstrated based on optical ring resonators [71], Mach-Zehnder delay interferometer [401], and arrayed waveguide grating [402]; integrated OEOs were also reported although the phase noise performance still needs improvement [403]. In addition, some multifunctional building blocks such as reflective-type microring resonator [404] and programmable 2D mesh network [405] have been demonstrated, which might be useful for reconfigurable or software-defined microwave photonic radar.…”

As the only method for all-weather, all-time and longdistance target detection and recognition, radar has been intensively studied since it was invented, and is considered as an essential sensor for future intelligent society. In the past few decades, great efforts were devoted to improving radar's functionality, precision, and response time, of which the key is to generate, control and process a wideband signal with high speed. Thanks to the broad bandwidth, flat response, low loss transmission, multidimensional multiplexing, ultrafast analog signal processing and electromagnetic interference immunity provided by modern photonics, implementation of the radar in the optical domain can achieve better performance in terms of resolution, coverage, and speed which would be difficult (if not impossible) to implement using traditional, even state-of-the-art electronics. In this tutorial, we overview the distinct features of microwave photonics and some key microwave photonic technologies that are currently known to be attractive for radars. System architectures and their performance that may interest the radar society are emphasized. Emerging technologies in this area and possible future research directions are discussed.

“…In addition to the MRR group delay architectures, TTDs can also be composed of a Mach-Zehnder delay interferometer (MZDI) and a MZI [45,65], and these can be called MZI delay architectures. In this architecture, MZDI is used to tune the phase or time delay of the optical carrier, in which the power coupling ratio of the upper to lower arms is varied by the MZI.…”

“…The size and weight of OBFNs are intuitive performances corresponding to the number of free-space components and fiber components used in architectures [14]. The power consumptions of OBFNs are mainly induced by lasers, except for the electric and photonic amplifiers [65]. Here, the power consumptions of OBFNs are simply evaluated using the number of lasers applied in these architectures.…”

With the rapid data growth driven by smart phone, high-definition television and virtual reality/augmented reality devices and so on, the launched 5G and upcoming 6G wireless communications tend to utilize millimeter wave (mmWave) to achieve broad bandwidth. In order to compensate for the high propagation loss in mmWave wireless communications and track the moving users, beamforming and beamsteering are indispensable enabling technologies. These have promising potential to be realized through the use of optical beamforming networks (OBFNs) that have a wider bandwidth and smaller size, lower power consumption, and lower loss compared to those of their electric counterparts. In this paper, we systematically review various OBFN architectures using true time delays and optical phase shifters, as well as discuss performances of different architectures, scalable technologies that promote the advancement of OBFNs, and the application potentials of OBFNs. Two-dimensional OBFNs with discrete components or integrated optical devices have been elaborated, in addition to one-dimensional architectures. Moreover, the state-of-the-art technologies relative to reducing the size, loss and nonlinearity of OBFNs have also been discussed here.

Integrated photonics is poised to become a mainstream solution for high-speed data communications and sensing in harsh radiation environments such as outer space, high-energy physics (HEP) facilities, nuclear power plants, and test fusion reactors. Understanding the impact of radiation damage in optical materials and devices is thus a prerequisite to building radiationhard photonic systems for these applications. In this paper, we report real-time, in-situ analysis of radiation damage in integrated photonic devices. The devices, integrated with an optical fiber array package and a baseline-correction temperature sensor, can be remotely interrogated while exposed to ionizing radiations over a long period without compromising their structural and optical integrity. We also introduce a method to deconvolve the radiation damage responses from different constituent materials in a device. The approach was implemented to quantify Gamma radiation damage and post-radiation relaxation behavior of SiO2-cladded SiC photonic devices. Our findings suggest that densification induced by Compton scattering displacement defects is the primary mechanism for the observed refractive index change in SiC. Additionally, post-radiation relaxation in amorphous SiC does not restore the original pre-irradiated structural state of the material. Our results further point to the potential of realizing radiation-hard photonic device designs taking advantage of the opposite signs of radiation-induced refractive index changes in SiC and SiO2.
