Do's and Don'ts When Visiting Circularly Polarized Luminescence
Advanced Optical Materials, Volume 14, Issue 11, 20 March 2026.This perspective presents our insights into the principles, challenges, and opportunities of circularly polarized luminescence (CPL). Highlighting key concepts such as the dissymmetry factor (glum) and molecular design strategies, we discuss advances in CPL efficiency, emerging NIR emitters, solid‐state applications, and the growing role of theory and ...

Optimization of photon storage fidelity in ordered atomic arrays
New Journal of Physics, 2018 A major application for atomic ensembles consists of a quantum memory for light, in which an optical state can be reversibly converted to a collective atomic excitation on demand. There exists a well-known fundamental bound on the storage error, when the

Light‐Coupled Nanocrystal Solids
ChemistryEurope, Volume 4, Issue 3, March 2026.Light‐coupled nanocrystal solids are self‐assembled superlattices or doped solids engineered for emission rather than charge transport, spanning optically dense to dilute regimes and enabling collective or single‐photon optical functionalities. Defining the optical coupling and engineering these nanomaterials will expand applications of colloidal ...

Polarization control of radiation and energy flow in dipole-coupled nanorings
New Journal of Physics, 2020 Collective optical excitations in dipole-coupled nanorings of sub-wavelength spaced quantum emitters exhibit extreme sub-radiance and field confinement facilitating an efficient and low-loss ring-to-ring energy transfer.

Superradiance in Organic Dyes [PDF]
The characteristics of the superradiance in organic dyes pumped by a N_2 laser have been studied. It is confirmed that the experimental results satisfy the theoretical characteristics of the superradiance in a two level system, though the dyes employed ...

Bandgap Engineering On Demand in GaAsN Nanowires by Post‐Growth Hydrogen Implantation
Small, Volume 22, Issue 7, 2 February 2026.The GaAsN bandgap in the GaAs/GaAsN core–shell nanowire shifts to lower energy for increasing N concentrations. By post‐growth H implantation the GaAsN bandgap is moved to a higher GaAs‐like energy through the formation of N–H complexes. By thermal annealing, these complexes can be partially dissolved, allowing to tune the GaAsN bandgap over a range of

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.
