Reducing the Threshold of Organic Polariton Lasers by Active Layer Micropatterning and Lateral Confinement

Small Structures, Volume 7, Issue 5, May 2026.
The study demonstrates the miniaturization of organic polariton VCSELs based on BSBCz. Using ultra‐thin shadow masks, isolated microcavities as small as 5 µm are fabricated. These devices achieved record‐low lasing fluences (0.21 µJ/cm2), far below reference devices.

Modular Fabrication of Quantum‐Dot–Plasmonic Metasurfaces for Tailored Optical Modes

Small Structures, Volume 7, Issue 5, May 2026.
Our modular photonic architecture is illustrated using color‐coded building blocks representing colloidal quantum dots, gold nanoparticles, and thin films. This visual metaphor highlights our bottom‐up and top‐down fabrication approach, enabling the creation of tailored optical modes for optoelectronic applications.

Role of Anharmonicity and Bimetallic Intermixing in the IR and Raman Spectra of Cun$_{n}$ and Pdn$_{n}$Cu6−n$_{6-n}$ Clusters (n<7$n\lt 7$). Ab Initio Benchmarking of DFT

Small Structures, Volume 7, Issue 5, May 2026.
High‐level ab initio and density functional theory calculations reveal a structural and spectroscopic transition from pla nar Cu6 to three‐dimensional Pd6, whose lowest energy triplet state undergoes a Jahn‐Teller distortion. This evolution from molecule‐like to metal‐like bonding produces distinct infrared and Raman fingerprints, providing reliable ...
