Chalcogen Alloy‐Engineered Te2Se/Si Heterojunctions for Low‐Noise Complementary Metal‐Oxide Semiconductor‐Compatible Short‐Wave Infrared Imaging

Advanced Optical Materials, EarlyView.
A Te2Se/Si heterojunction designed through atomistic simulations reduces oxide‐related traps, dark current, and noise compared with pure tellurium devices. This CMOS‐compatible platform enables short‐wave infrared detection and high‐contrast imaging in a 14 × 14 array, highlighting a scalable strategy for robust, low‐noise SWIR photodetectors and image

Photoluminescent Color Centers on a Mainstream Silicon Photonic Foundry Platform

Advanced Optical Materials, EarlyView.
Silicon photonic chips route and process light efficiently but are inherently inefficient at generating it. Here, bright light‐emitting defects, W‐centers, are written into the silicon layer of finished chips from a mainstream commercial foundry: high‐energy ions are implanted straight through the protective oxide and activated by a 250∘C$^\circ{\rm C}$

Sub‐Diffraction and Irreversibly Tunable Imaging With Potato Starch Lenses

Advanced Optical Materials, EarlyView.
Native potato starch granules function as sustainable birefringent microlenses that enable polarization‐controlled conventional and vortex lensing via spin‐to‐orbital angular momentum conversion. They provide sub‐diffraction and spiral‐contrast imaging, support vortex‐array generation with controllable topological‐charge sign, exhibit irreversible ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Asymmetry in Skipping Enhances Viability Against Control Input Noise

Advanced Robotics Research, EarlyView.
Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...
