Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes

Advanced Optical Materials, EarlyView.
This study explores spectrally tunable photonics barcodes using carbonized polymer dots (CPDs) based on whispering gallery mode (WGM) photoluminescence. CPDs offer wavelength‐dependent emission from visible to near‐infrared (NIR), thereby enabling variable WGM emissions.

Low‐Loss Parowax‐Imprinted Diffractive Neural Network for Orbital Angular Momentum Terahertz Holographic Imaging

Advanced Photonics Research, EarlyView.
This work introduces a low‐loss diffractive neural network, fabricated using an imprinting technique with parowax material, for recognizing and manipulating the topological charge of orbital angular momentum (OAM) waves. It is also demonstrated that the low‐loss diffractive network can perform mathematical operations based on the topological charges of

Improving Light Outcoupling and Addressing Measurement Specifics in Perovskite Light‐Emitting Diodes with Light Management Foils

Advanced Photonics Research, EarlyView.
The necessity and feasibility of enhancing light outcoupling in perovskite light‐emitting diodes (PeLEDs) is highlighted. On near‐IR PeLEDs, low‐cost, micro‐textured light management (LM) foils demonstrate boost in light extraction. Optimizing perovskite thickness and the optical cavity in synergy with LM foils is crucial for maximizing performance ...

Imaging Photonic Resonances within an All‐Dielectric Metasurface via Photoelectron Emission Microscopy

Advanced Photonics Research, EarlyView.
Photonic resonances within a dielectric metasurface are investigated using photoelectron emission microscopy (PEEM) and finite‐difference time‐domain simulations. An electron inelastic mean free path of 35 ± 10 nm is extracted from comparisons between microscopy and simulations.

940 nm Micro‐Light‐Emitting Diode Fabricated on Industry‐Compatible 300 mm Si (100) Substrate by Metal–Organic Chemical Vapor Deposition

Advanced Photonics Research, EarlyView.
The fabrication of 940 micro‐light‐emitting diodes on both 300 mm Si and Ge/Si wafers has been demonstrated using direct metal–organic chemical vapor deposition epitaxy. These promising results show the potential for monolithic integration of III‐As onto complementary metal‐oxide‐semiconductor (CMOS)‐compatible silicon platforms. This achievement opens
