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

open access: yesAdvanced 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

Enabling low Threshold Laser Through an Asymmetric Tetramer Metasurface Harnessing Polarization‐Independent Quasi‐BICs

open access: yesAdvanced 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‐

Unidirectional Focusing of Light Using Structured Diffractive Surfaces

open access: yesAdvanced Optical Materials, EarlyView.
This study presents a reciprocal diffractive unidirectional focusing design based on linear and isotropic layers. A set of cascaded diffractive layers is designed using deep learning to achieve efficient forward light focusing while suppressing backward propagation across various illumination angles.

Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.

Toward Direct Laser Writing of Dual‐Layer Metasurfaces with the Plasmonic Phase‐Change Material In3SbTe2

open access: yesAdvanced Optical Materials, EarlyView.
A simple optical programming technique is developed for fabricating plasmonic nanoantennas in a dual‐layer metasurface by crystallizing the plasmonic phase‐change material In3SbTe2 from the top and through the substrate with a subsequent reamorphization step.
