Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

Advanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...

Fold Walker: An Origami‐Inspired Quadruped Robot for Multipattern Locomotion and Object Grasping

Advanced Robotics Research, EarlyView.
This article presents Fold Walker, an origami‐inspired quadruped robot capable of multipattern locomotion and object grasping. With each leg featuring two rotational folds, the robot can transform from a flat 2D configuration into complex 3D poses. Furthermore, its trunk and legs can be one‐shot 3D printed as a unified structure, greatly simplifying ...
