Among these are the helicity of electromagnetic fields described with the optical chirality density and emitters sensitive to circular polarization employed in quantum communications. In the weak coupling regime of chiral emitters, we analyze the conversion of chirality which can be regarded as an analogue to absorption of energy describing the change of circular polarization of the incident field. This enables the tailoring of chiral near-fields close to metamaterials, e.g. composed of gold helices, and gives insights into extinction measurements such as circular dichroism. We show relation of the weak and strong coupling regime. The latter can be modelled with cross electric-magnetic polarizabilities or with effective chiral materials, i.e. bi-anisotropic media. Accordingly, we motivate the necessity for rigorous numerical simulations to accurately describe chiral light-matter interaction.}, language = {en} } @misc{GutscheBurgerNietoVesperinas2017, author = {Gutsche, Philipp and Burger, Sven and Nieto-Vesperinas, Manuel}, title = {Fundamentals and Applications of an Optical Theorem for Chiral Optical Fields}, journal = {4th International Conference on Optical Angular Momentum}, year = {2017}, abstract = {The helicity of light is of great interest in both fundamental research and in applications such as dichroism spectroscopy. Its time-harmonic formulation is directly proportional to the density of optical chirality. Recently, both an helicity optical theorem (HOT) and a chirality conservation law (CCL) have been formulated for arbitrary scatterers taking into account an underlying continuity equation of this quantity. We summarize these two equivalent fundamental laws and analyze their potential applications.}, language = {en} }
