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 ...

Engineering Exciton g‐Factors With Light in Type‐II Heterostructures
Advanced Optical Materials, EarlyView.All‐optical approaches have emerged as cutting‐edge alternatives for ultrafast, energy‐efficient, and spatially localized tuning and switching of material properties. In our work, we demonstrate how light intensity alone can be leveraged to engineer g‐factors from a single‐type of carrier in type‐II heterostructures through Coulomb‐induced wavefunction

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 ...

Tunable Quasi‐Resonances in Polypyrrole Nanodisks
Advanced Optical Materials, EarlyView.Polaronic carrier absorption enables electrochemically switchable quasi‐resonances in conducting polymer nanoantennas. ABSTRACT Redox‐tunable conducting polymers have emerged as promising materials for dynamic plasmonics and metasurfaces. However, only a few conducting polymers with particularly high conductivities (>1000 S/cm) have been reported to ...

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.
