Frequency‐Selective Terahertz Wave Amplification by a Time Boundary in Huygens' Metasurface

Advanced Optical Materials, EarlyView.
In a free‐standing all‐dielectric Huygens' metasurface, ultrafast pulsed laser excitation is used to establish the time boundary for a coherent modulation to the electric and magnetic polarizability in the adiabatic limit. Amplification of THz waves at frequencies that can be continuously tuned have been achieved, showing an effective energy gain up to

Comparative Test of Novel Fluorescent Optical Antennas for LED‐ and Laser‐Based Optical Wireless Communications

Advanced Optical Materials, EarlyView.
New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.

Red Multi‐Resonant Thermally Activated Delayed Fluorescence Emitters as Bioimaging Agents

Advanced Optical Materials, EarlyView.
Multi‐resonant thermally activated delayed fluorescence (MR‐TADF) emitters have attracted strong interest for use in electroluminescent devices due to their high photoluminescence quantum yield and narrowband emission. These properties, along with red emission, are also crucial for bioimaging probes.

Elucidating and Biomimicking the Coloration Mechanisms Responsible for the Vibrant Blue Hues of the Common Kingfisher

Advanced Optical Materials, EarlyView.
This study reveals why the back feathers of a common kingfisher show various non‐iridescent blueish structural colors by analyzing the internal structures of the feathers. It demonstrates how structural differences lead to the different optical interactions, thereby producing different colors.

Optimized Growth and Manipulation of Light–Matter Interaction in Stabilized Halide Perovskite Nanowire Array

Advanced Optical Materials, EarlyView.
This study investigates CsPbBr3 nanowire (NW) array synthesis and stability using nanoporous anodized aluminum oxide (AAO) templates. Simulations identify optimal pore geometries for light–matter interactions (LMI). The ligand‐free modified inverse temperature crystallization (ITC) method is utilized for NW array growth, providing insights into a broad

The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

Advanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

3D Printed Optics Achieves Broadband Structured Light

Advanced Optical Materials, EarlyView.
The arbitrary creation of structured light often requires complex design and fabrication steps and is largely limited to single wavelength. By leveraging off the toolkit for digital holograms, how complex amplitude modulation can be implemented as 3D printed optics in a manner that is broadband is shown, for the creation of multiwavelength forms ...

Simultaneous Perfect Anomalous Reflection and Angle of Arrival Sensing in Reconfigurable Intelligent Surfaces

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.
