How “Empty Space” Is Supercharging Atomically Thin Semiconductors

How “Empty Space” Is Supercharging Atomically Thin Semiconductors

A single layer of atoms may seem too thin to meaningfully interact with light, yet materials like tungsten disulfide are reshaping what is possible in nanophotonics. Researchers have now found a way to dramatically strengthen these interactions. Atomically thin semiconductors such as tungsten disulfide (WS₂) are emerging as key materials for next-generation photonic technologies. Although [...]

Net gain via optical parametric amplification in photonic chips integrated with 2D materials

On-chip integration of two-dimensional (2D) materials provides a promising route for implementing nonlinear integrated photonic devices that break existing barriers and unlock new capabilities. Although 2D materials with ultrahigh optical nonlinearity have driven this technological progress, t...
