Advanced Optical Materials, EarlyView.Femtosecond TAS measurements on perovskite nanocrystals reveal how the one‐photon absorption cross‐section scales linearly with nanocrystal volume, independent of shape. In contrast, biexciton Auger lifetimes vary strongly with shape and remain constant in the weak confinement regime for nanocrystals larger than the exciton Bohr radius, offering new ...

Advanced Photonics Research, EarlyView.The fabrication of 940 micro‐light‐emitting diodes on both 300 mm Si and Ge/Si wafers has been demonstrated using direct metal–organic chemical vapor deposition epitaxy. These promising results show the potential for monolithic integration of III‐As onto complementary metal‐oxide‐semiconductor (CMOS)‐compatible silicon platforms. This achievement opens

Advanced Photonics Research, EarlyView.In this study, it implements a high‐efficiency polarization‐entangled photon source based on single‐mode fiber coupling with a spectral brightness exceeding 2.0 MHz mW−1 nm−1, utilizing a spatial mode‐matching technique. The results of this study provide a more intuitive and practical guide for implementing high‐efficiency quantum light sources ...

Advanced Robotics Research, EarlyView.Inflatable kirigami crawlers are fabricated from heat‐sealable textiles and achieve motion through cyclic pneumatic actuation. Strategically placed kirigami cuts guide asymmetric deformation, doubling contraction compared to traditional pouches and forming scale‐like surfaces.
