Breakthrough Nanodisk Revolutionizes Photonics Research

Chalmers University researchers create a compact nanodisk with unprecedented optical properties, promising advancements in nonlinear optical devices.

Researchers at Chalmers University of Technology have combined nonlinear and high-index nanophotonics into a single nanodisk.
The nanodisk, made from molybdenum disulfide, is a thousand times thinner than human hair and highly efficient at converting light frequencies.
This new nanostructure maintains and enhances the nonlinear optical properties of its material, despite challenges in maintaining crystalline lattice symmetry.
The nanodisk's high refractive index and ability to localize electromagnetic fields make it a powerful tool for second-harmonic generation.
Potential applications include integration into optical circuits and miniaturization of photonics, with significant implications for communications, medicine, and quantum technologies.
