WebMay 8, 2024 · When light is circularly or elliptically polarized, its orthogonally coupled electric and magnetic fields oscillate in a left- or right-handed helix (chiral) geometry. Likewise, a light with OAM typically exhibits a helical (chiral) wavefront shape. Thus, both SAM and OAM play a role in the chirality of light. WebSep 2, 2024 · We aim to present the importance of understanding the properties that give light chirality, light–matter interactions, and the resultant chiroptical phenomena in applications such as chiral sensing.
