Magnetic Steganography Based on Wide‐Field Diamond Quantum Microscopy
Advanced Optical Materials, EarlyView.This document illustrates magnetic steganography. Magnetic graphics, including pixel art and QR codes, are produced using magnetic materials (such as Ni) and obscure behind patterns manufactured using non‐magnetic materials (such as Au), which are unveiled through widefield quantum microscopy. Furthermore, manipulating the electron spin of NV with dual

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

Mitigating Losses in Hyperbolic Asymptotic Eigenmodes
Advanced Photonics Research, EarlyView.Herein, hyperbolic asymptotic eigenmodes, high‐k modes aligned with asymptotic directions in hyperbolic metamaterials, are introduced. By tuning permittivity tensors to balance loss compensation (Re(ε∥)/Re(ε⊥)=Im(ε∥)/Im(ε⊥))$\left(\right. \text{Re} \left(\right. \left(\epsilon\right)_{\parallel} \left.\right) / \text{Re} \left(\right.
