    Description

    Many phenomena in nature, including multiple biochemical processes, are governed by the fundamental property of chirality. An object is called chiral when its mirror image cannot be superimposed with the original object, and many examples of chirality can be found at all scales in nature, from organisms to biomolecules and amino acids, which often occur only in one handedness. Circular dichroism spectroscopy was suggested as a powerful optical technique to study chiral materials and molecules. In natural media, chiral effects are weak, so that chiral metamaterials were suggested for achieving strong chiroptical responses. In this project, we aim to address a big challenge in nanophotonics by developing novel dielectric metaphotonic structures to enhance chiroptical signals a hundredfold and achieve maximal chirality with the help of structured resonant surfaces and employ these findings for developing several key applications.
