Chiral Nanomaterials: Enantiomorphing Chiral Plasmonic Nanostructures: A Counterintuitive Sign Reversal of the Nonlinear Circular Dichroism (Advanced Optical Materials 14/2018)

Owing to recent advances in theory and nanofabrication, chirality parameters enabled spectacular optical properties – negative refractive index, superchiral light – in chiral nano/metamaterials. Nanofabrication allows physical tuning of the chirality parameters. In article number 1800153, Xuezhi Zheng, Ventsislav K. Valev and co‐workers illustrate this concept for the first time, morphing the dimensions of one chiral form into another (“enantiomorphing”), via achiral states. The image shows the enantiomorphing of chiral crosses.
