Scientists from China have developed high-performance colloidal quantum-dot (CQD)  surface-emitting laser array based on circular Bragg resonator (CBR). The CQD CBR laser array, leveraging high-quality CQD material with low gain threshold and high stability and CBR cavity with strong optical confinement, features a low lasing threshold, high pixel density (2100 PPI), and a remarkable 1000-hour operation lifetime (3.63 × 10⁸ pulses) at room temperature, promising advancements for practical CQD laser applications in the future.

The authors explored the recombination dynamics and defect concentration of a mixed cation mixed halide perovskite Cs_0.17FA_0.83PbI_1.8Br_1.2 with 1.75 eV bandgap after exposure to a gamma-ray source (2.5 Gy/min). The manuscript shed light on the use of the wide bandgap perovskite Cs_0.17FA_0.83PbI_1.8Br_1.2 as a material for tandem solar cells with potential applications in a space environment.

Researchers in China have proposed and experimentally demonstrated a revolutionary metamaterial agent, termed metaAgent. This intelligent EM system integrates reasoning and cognitive capabilities, enabling autonomous task planning and execution in real-time environments. Unlike traditional metamaterials that rely on predefined functionalities, metaAgent leverages deep learning and foundation models to reason in natural language and interact with both humans and robots. It masters complex EM manipulation tasks, opening new frontiers for cognition radar, human-robot interaction within future smart environments, and so on.

Researchers propose a novel mechanism for non-reciprocal optical devices without magnetic fields through nonlinear non-reciprocal susceptibility. They experimentally achieved self-induced isolation of optical signals, demonstrating high isolation ratio (63.4 dB), wide bandwidth (2.1 GHz), and low insertion loss (1 dB). The innovation enables passive isolation through asymmetry cavity, allowing a weak signal to control stronger backward laser. This advancement has implications for topological photonics and quantum information transfer.

Optical sectioning enables precise 3D imaging by extracting signals in focus and eliminating out-of-focus backgrounds. Scientists in China review various optical sectioning methods from the perspective of off-axis and coaxial imaging, assess the performance, and provide guidance on their applications. Finally, it discusses the advantages of off-axis separated detection over coaxial imaging and the versatility of a single system to accommodate diverse sectioning methods, potentially revolutionizing 3D bioimaging.
