Chiral supramolecular electronics for high‐efficiency circularly polarized organic light‐emitting diodes

FlexMat, EarlyView.
This perspective highlights supramolecular strategy for achieving band‐level chirality in vacuum‐deposited triazatruxene thin films, enabling circularly polarized organic light‐emitting diodes (OLEDs) with both high dissymmetry factor and external quantum efficiency, thereby overcoming the longstanding efficiency‐dissymmetry trade‐off in circularly ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

Laser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

Laser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.
