Chiral resonant metaphotonics

Fixed price - 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 for the study of chiral materials and molecules. It gives access to an enantioselective signal based on the differential absorption of right and left circularly polarized light. However, in natural media, chiral effects are very weak, so that chiral plasmonic structures and chiral metamaterials have been suggested for achieving much stronger chiroptical responses in a controllable way.
