Bowtie structure (IMAGE) Technical University of Denmark Caption Illustration of the new bowtie structure, which can be seen in the middle of the picture. The bowtie structure compresses light spatially, and the nanostructures around it store it temporally. The result is a compression of light to the smallest scale to date – the world's smallest photon in a dielectric material. Credit Illustration: DTU.
