Engineered Growth of Perovskite Nanocrystals on Graphene with Subsequent TiO2 Integration for Enhanced Photodetection and Environmental Catalysis

open access: yesAdvanced Optical Materials, EarlyView.
The growth of perovskite nanocrystals on graphene, coupled with an optically active and protective oxide interface, enhances photodetection and environmental catalysis by facilitating efficient charge separation, improved light absorption, and enhanced structural stability, offering a promising approach for advanced optoelectronic and catalytic ...

Mechanically Tunable Optical Response in Silicon Nanosphere Metasurface Fabricated via Bottom‐Up Process

open access: yesAdvanced Optical Materials, EarlyView.
A large area mechano‐tunable square lattice array of silicon nanospheres is fabricated by a bottom‐up process, and the capability to tune the lattice resonances by external strain is demonstrated. Spectrally overlapping the electric and magnetic dipole lattice resonances by mechanical strain induces the lattice Kerker effect and strongly suppresses the

Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings

open access: yesAdvanced Photonics Research, EarlyView.
The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...

Synthesis and Optical Properties of Single‐Crystalline Phosphors Gd3In2Ga3O12:RE3+ (RE = Nd3+ and Ho3+) Grown via the Optical Float Zone Method

open access: yesAdvanced Photonics Research, EarlyView.
Nd3+‐ and Ho3+‐doped Gd3In2Ga3O12 single crystals have been successfully synthesized via the optical float zone method. Their structure and optical characterization demonstrate efficient narrow‐line 4f–4f emission, low cross‐relaxation, and bright photoluminescence, indicating their potential as advanced optical materials for photonic applications.

Design and Characterization of Low‐Threshold InP Nanowire Photonic Crystal Surface‐Emitting Lasers

open access: yesAdvanced Photonics Research, EarlyView.
The lasing performance of nanowire (NW) photonic crystal surface‐emitting lasers (PCSELs) is highly sensitive to changes in the photonic crystal lattice constant and the NW diameter. This study systematically investigates the threshold power and the threshold gain for different PCSEL geometries.
