Manipulating Transverse Spin Angular Momentum with Symmetrically Modulated Hybridly Polarized Vector Optical Field

Transverse spin angular momentum (SAM) of photon, also known as ‘photonic wheel’, has attracted much attention, owing to its extraordinary properties and broad application prospect. Thus, it is essential flexibly manipulate the transverse SAM in order satisfy different needs. In this article, we design generate a new kind symmetrically modulated hybridly polarized vector optical field (SM-HP-VOF), pure can be achieved based on tightly focused SM-HP-VOF. Through adjusting parameters SM-HP-VOF, shape, intensity, symmetry modulated. Moreover, by adding segmented vortex phase distribution becomes more concentrated stronger, indicating that orbital catalyst modulating SAM. Such results provide avenue studying SAM, which would have potential applications various areas including chip circuitry, quantum computing, trapping manipulation.
