Using the nonseparability of vector beams to encode information for optical communication
In this work, it is experimentally demonstrated that the nonseparability of vector beams (eg,
radial and azimuthal polarization) can be used to encode information for optical …

Temporal effect of the spin-to-orbit conversion in tightly focused femtosecond optical fields
Spin and orbital angular momenta are two of the most fundamental physical quantities that
describe the complex dynamic behaviors of optical fields. A strong coupling between these …
