Atomically thin semiconductors such as tungsten disulfide (WS2) are promising materials for future photonic technologies. Despite being only a single layer of atoms thick, they host tightly bound ...
A single layer of atoms may seem too thin to meaningfully interact with light, yet materials like tungsten disulfide are ...
A new publication DOI 10.29026/oea.2026.250193 discusses electric-field-induced second-harmonic generation paves the way for next-generation nonlinear photonics ...
High-order harmonic generation (HHG) — a technique that converts light into much higher frequencies — is an essential tool for exploring otherwise inaccessible parts of the electromagnetic spectrum.
