Optical circular helicity
WebMar 9, 2024 · Previous studies have demonstrated helicity-dependent optical control of spatial chirality and magnetization . The former is central for asymmetric synthesis in chemistry and homochirality in bio-molecules, while the latter is of great interest for ferromagnetic spintronics. WebFeb 23, 2024 · All-optical helicity dependent switching (AO-HDS), deterministic control of magnetization by circularly polarized laser pulses, allows to efficiently manipulate spins without the need of a magnetic field. However, AO-HDS in ferromagnetic metals so far requires many laser pulses for fully switching their magnetic states.

WebNov 11, 2024 · Detection of circularly polarized light (CPL) has a high potential for development of various optical technologies. Conventional photodetectors require optical polarizers on the device to detect polarized light, and this causes substantial losses of sensitivity and resolution in light detection. WebIt is also evident that both the helicity of the incident fields and the dual-symmetry (or helicity preserving nature) of a photonic structure are essential in circular dichroism enhancement effects . Reconciling our understanding of both microscopic and macroscopic sources of helicity in a general theoretical model, however, is an ongoing ...
