Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams

Advanced Optical Materials, EarlyView.
Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.

Bis‐Naphthyl Dipicolinic Dicarboxamide‐Based Self‐Assembled Aqueous Nano Dispersion as an Efficient Light Harvesting Medium and Cucurbit[7]Uril Host Complexation Effect Study

Advanced Optical Materials, EarlyView.
Bis‐naphthyl‐4‐hydroxy‐dipicolinic‐dicarboxamide, a small molecule, forms nanodispersion as an efficient light‐harvesting medium in aqueous solution. Further cucurbit[7]uril addition was found to inhibit the FRET co‐assembly by host‐guest complexation. ABSTRACT Development of artificial light harvesting systems in a minimalistic self‐assembly model is ...

Phonon Polariton Confinement in Isotopically Pure MOVPE‐Grown BN Triangles

Advanced Optical Materials, EarlyView.
Phonon polaritons are confined in MOVPE‐grown isotopically pure 10BN$^{10}{\rm BN}$ triangles. The resonator modes are excited and mapped by near‐field spectroscopy. Through scanning a wide infrared frequency range and modeling, the polariton dispersion relation is retrieved.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling

Advanced Optical Materials, EarlyView.
Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...

Strong Photoluminescence Enhancement in All‐Dielectric Ge Thin Film Metasurfaces for Integration on the Si Platform

Advanced Optical Materials, EarlyView.
Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.
