3D Meta‐Atoms for High Confinement of Mid‐IR Radiation
Advanced Optical Materials, EarlyView.Mid‐infrared, three‐dimensional circuit‐like resonators with extreme field confinement are experimentally demonstrated. Combining simulations, measurements, and analytical modelling, a physical interpretation and prediction of the resonant modes supported by the structure, including their resonant frequency and radiative and non‐radiative losses, is ...

A fixed point theorem for distributions
Stochastic Processes and their Applications, 1992 The author studies, in a systematic form, the contractive behavior of the map \(S\) of distributions to distributions \(S(F)\overset{\mathcal D}=\sum_ i T_ i X_ i+C\), \((C,T=(T_ 1,T_ 2,\dots))\), \(X_ i\) are independent random variables with distribution function \(F\). Further the author obtains the higher and exponential moments of the fixed point.

Quantum Emitters in Rhombohedral Boron Nitride
Advanced Optical Materials, EarlyView.Rhombohedral boron nitride (rBN) is an emerging wide‐bandgap van der Waals (vdW) material with strong second‐order nonlinear optical properties. In this work, optically‐addressable spin defects and single‐photon emitters (SPEs) are fabricated deterministically in rBN.

Optical Poling of Ferroelectric Liquids
Advanced Optical Materials, EarlyView.The optical control of size and shape of polar domains in ferroelectric nematic liquid crystal cells is reported. In sufficiently thin samples, light irradiation induces the formation of a novel singular spiral‐shape arrangement of the polar director as a response to localized illumination.

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review
Advanced Photonics Research, EarlyView.Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...
