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$^\circ{\rm C}$

Advanced Optical Materials, EarlyView.Metallic dimer antennas on top of the phase‐change material Ge3Sb2Te6 are addressed with laser pulses, resulting in inhomogeneous crystallization. A self‐consistent multiphysics model is employed to simulate the crystallization and to understand the resulting shift of the antenna resonance.

Advanced Optical Materials, EarlyView.Disordered plasmonic metasurfaces enable advanced control over light scattering through disorder engineering. A theoretical model based on multiple scattering theory is developed to predict the coherent reflection and transmission of light from disordered metasurfaces with arbitrary pair correlations.

Advanced Optical Materials, EarlyView.A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
