Integrated microwave photonic chip: toward full spectrum wireless communication
Jianping Yao
This commentary highlights a breakthrough thin-film lithium niobate (TFLN) photonic transceiver that enables broadband wireless communications from 5 to 100 GHz. The system integrates optoelectronic oscillators (OEOs) to generate the transmitter carrier and receiver local oscillator signals, achieving 100 Gbps transmission with intelligent frequency reconfiguration. This represents a major step toward flexible, spectrum-agile, and scalable 6G wireless systems.

Ultra-thin meta-platform for vectorial holography
Hyeonsu Heo and Junsuk Rho
This commentary article highlights a recently published work on an ultra-thin metasurface platform for the generation of vectorial holography. The proposed generic metasurface design strategy enables the generation of complex and arbitrary vectorial holographic images with high efficiency, which holds strong potential for various applications such as photonic encryption, optical cryptography, and anti-counterfeiting technologies.

Divide and conquer: parallel processing in computational imaging
David J. Brady
Parallel processing in array cameras enables improvements in field of view, depth of field as well as color and polarization sampling. A recent study by Zhang et al. expands on this theme with the demonstration of “SpeedShot,” which uses a small camera array to improve temporal sensitivity. Here we review the context in which SpeedShot was developed and consider the roadmap for continued improvements in parallel camera systems.

Learning deeply to vanish light: intelligent metasurface design for next-generation antireflection
Yuheng Chen, Vaishnavi Iyer, Alexander V. Kildishev, Vladimir M. Shalaev, and Alexandra Boltasseva
The commentary discusses recently published design for antireflective coating on solar cells. The proposed free-form inverse design, based on single-layer silicon metasurfaces, dramatically suppresses broadband optical reflection from silicon surfaces.

Acoustic resonances of biological nanoparticles
Gregory V. Hartland
Laser excitation of nanoparticles can excite vibrational modes of the particles that correspond to changes in size and shape. The frequencies and lifetimes of these modes provide information about the mechanical properties of the particles, and how they interact with their environment. Studies of these modes in virus particles can thus provide unique information about viruses, and how their properties change during their lifecycle.

Advancing perovskite photovoltaics for space: critical stability testing guidelines
Yifan Zheng, Guodong Zhang, Zicai Shen, Jianhui Bin, Deying Luo, Rui Zhu, and Yuchuan Shao
Low-Earth orbit, the primary operational domain for the international space station and commercial satellites, presents a severe thermodynamic environment for spacecraft. Current testing methodologies, such as thermal cycling and damp-heat assessments, are inadequately aligned with the characteristics of perovskites. The commentary suggests a tiered thermal stress testing framework to enhance existing standards and support a robust and standardized framework for certification.
