Advanced Optical Materials, EarlyView.A reconfigurable intelligent surface is proposed that can simultaneously anomalously reflect the light and sense the angle of arrival. An in situ optimization of either the currents flowing on array elements or the far field in the receiver direction realizes anomalous reflection and suppresses parasitic scattering.

High‐Performance and Ultrafast Single Germanium Nanowire Photodetectors
Advanced Optical Materials, EarlyView.Semiconductor nanowire‐based photodetectors with high sensitivity and fast photoresponse in the near‐infrared wavelength range are crucial for applications in light‐wave communication switches, as well as environmental and atmospheric sensing. Here, the fabrication of an axial p‐n junction along single germanium nanowires and their photoresponse ...

Advanced Optical Materials, EarlyView.Light impinging from the left on a metasurface composed by active material. The metasurface shows asymmetric configuration through the non‐uniform presence of holes. The forming quasi‐BICs modes are exploited for lasing purposes. Abstract It is proposed and numerically demonstrated a novel strategy to achieve lasing generation from a dual‐band symmetry‐

Colossal Terahertz Emission with Ultrafast Tunability Based on Van der Waals Ferroelectric NbOI2
Advanced Optical Materials, EarlyView.The widespread THz applications are hindered by the scarcity of efficient ultrafast THz sources with on‐demand fast modulation and easy on‐chip integration capability. Here the discovery of colossal THz emission is reported from a van der Waals (vdW) ferroelectric semiconductor NbOI2 and demonstrates the ultrafast coherent control of the THz emission ...
