Chiral Properties of Light,ween such fields and chiral media. The results of these interactions depend on the mutual handedness of the field and the medium. Therefore, such interactions are the basis of chiroptical spectroscopy. In this chapter, we introduce optical chirality as a measure for the chiral interaction strength o

Enhancement of Chiral Fields by Geometrically Chiral Structures,, we analyze the chiral near-field response of different chiral nanostructures illuminated with circularly polarized light in this chapter. We show that properly designed planar geometrically chiral nanostructures can result in a natural spatial separation of chiral near-fields with opposite handedn

Chiral Fields of Macroscopically Achiral Arrangements,als, however, are unwanted for chiral plasmonic near-field sources, where the circular dichroism response of a chiral analyte should be enhanced. In this chapter, we introduce the concept of plasmonic racemates, which combine the strong chiral near-field response of chiral nanostructures with the ze

Chiral Eigenmodes of Geometrically Chiral Structures,s best fulfilled by the fundamental mode of a helix. Because the chiral near-fields are already generated by this chiral eigenmode, the incident light is only necessary to excite this mode. Based on this finding, we present a structure with multiple helices that provides strong chiral near-fields in

Comparison of Different Chiral Plasmonic Near-Field Sources,ngs of these approaches and compare the resulting near-field sources regarding their usability for chiroptical spectroscopy. We conclude that chiral eigenmodes carry the highest potential for sensitivity enhancement, while plasmonic racemates can be implemented in current circular dichroism spectros
